Passat (B5) :: P0411, P0011, P0300, P0301, P0303 - Misfire / Sputters And Hard To Drive
Aug 3, 2012
2002 Passat 1.8T
Backstory. The P0411 code shes had for quite some time. I think probably 4 years maybe. Just never did anything about it because I guess they are expensive to fix. Thats the SAIP and combi valve correct? Anyway to remove all the emissions stuff and get the codes deleted?
So, about 3 weeks ago, maybe a little longer i cleaned her engine bay, replaced a few vacuum lines because the shop she took it to last year did a terrible job. Mind you, they did a head gasket, timing belt and some other minor things while they were in there. And they couldn't take the time you run new vacuum lines, since they just cut the originals and used a bunch of t fittings to "solve" the problem.
Anyway, i replaced the lines and it seemed to run better at idle, still had a little mis at idle but ran smooth at speed. I also did an oil change, put some fuel injector cleaner in it, put some seafoam in the oil, and cleaned the engine bay thoroughly. I did it properly and took all the plastics off, cleaned them, scrubbed the bay and used an air hose to get rid of the excess water. Left in a nice state. Ran smoother, looked better, so on and so forth.
Fast forward to last week, and she mentions to me her car isnt running right. Its sputtering, hesitates, running rough, exhaust is puttering, and it used up a lot of gas. She parked it for a few days, and i came down to look at it. Mind you, i don't have a code reader. So I looked at it blindly thinking it had an ignition issue. Nothing could have changed that quick since i looked at it.
So, today we got one coil(just in case ones bad), and 4 new plugs (Autolite Iridiums). Replaced and gaped the plugs to .030, torqued to 23 ft/lbs and started the car. Seemed to run a bit better, but subsided quickly. I then pulled each coil harness plug to make sure it would misfire on each cylinder and it did. So, new plugs and the coils checked out. Time to get its codes read.
Took it to the Pepboys and the codes it came back with were the P0011, P300, P0301-3. Cleared the codes and they came back nearly immediately. I had the dreaded P0011 code. The misfire codes im guessing were from the coils being pulled on each one, and also due to the P0011. Now i read a lot of threads about the P0011 and how its usually not the camshaft position sensor. However, i pulled the plug on that while the car was running and nothing changed. So i thought it could be the CPS. Changed that out and still nothing.....

i have a 01 passat with a v6 in it on 4 motion and im having an issue with soem mis-firing
i pulled the codes. P0300 P0301 P0302 and P0303 which are all saying that there are missfires in cylander 1,2 and 3 and random miss fires.
im also getting a P0340 which is cam sensor A or the right hand bank. problem is i just replaced the cam sensor and when the motor got warm, the code came back. I was told by the previous owner that the car needed a Coolant Temp Sensor....can this be the cause of my mis-fire issue? hear me out.... it only happens when the car is warm so im thinking that the car is warm but the ecu thinks its cold cause its not getting a good signal from the CTS. thus its either advancing the timing as if the motor is cold and cuasing a miss fire or something along those lines. any thoughts?

2009 corolla 1.8l 155,000 miles. Replaced iridium spark plugs at 100,000
I got a CEL few weeks ago, P0301 Toyota - Cylinder 1 Misfire Detected
Car has been running bad for about 2 weeks now, excise noise on the highway, especially up hills.
Yesterday, I took a look, replaced the spark plug in cylinder 1, same results. Checked the coils using one of those flashing tools, all 4 flashed quickly, with no breaks in flashing. put it all back together, cleared the code, went home.
Took it out for a drive today, and it started running way worse. Checked the CEL, and now I have both P0301 and P0303 Misfire on cylinder 1 and 3. Barely made it home, ran VERY VERY bad.
Got home, and made a video of it. It just kept dying. Check it out here. [URL] .....
Also, when it does run, it almost sounds like I can hear excess air, its hard to hear in video, but doesn't sound right. Maybe air leak? How do I check?

I have a 02 Trailblazer that on Monday it gave me a code of P0300 (Random misfire), then two days later P0301 (Number one misfire); (I replaced plugs, boots and cam sensor) ran fine for 1 day now its a P0758 code (Shift solenoid B Electrical).

I have a 2001 Passat 1.8 Turbo engine trim is AUG. My car is acting funny since yesterday. When i start my car it idles rough and CEL start flashing but as soon as i drive at like 10-15 MPH speed it becomes smooth and CEL stops blinking. I took my car to autozone and have it scanned got P0340 P0300 P0301 and P0302. It means random misfire and misfire in cylinder 1 and 2. I am not getting the misfire code for cylinder 3AND 4.
I swap coil boot 1,2 with 3 and 4. But misfire didn't move with cylinder. So i waited whole night reset CEL and swap coil 1 with 4 and 2 with 3. Have i scanned again not i am getting P0300 = random misfire and P0302 = misfire in cylinder 2. I didn't get P0301 this time.

This morning I started my car and it was idling a little rough. The the Check Engine light began flashing - I immediately turned off the car and consulted this forum and my father the mechanic. After talking with my Dad and telling him that the car had sat for a week, he thought the issue was probably NOT the catalytic converter and thought it was probably related to the car sitting and possibly getting moisture in the gas. I started the car again (the roughness at idle seemed to have gone away) but the check engine light/malfunction indicator light (MIL) did not flash, it did come back on after a few seconds, but as a solid light . And as we've all read, it's OK to drive with a solid MIL.
I took the car over to Autozone and had the codes checked - P0300 (multiple cylinder miss fire) and P0301 (cylinder 1 misfire). I asked them to clear the codes. I has just put in new NGK spark plugs last month, so I didn't think it would be the plugs. I looked at a new coil pack for one of the cylinders. I decided to see if clearing the codes alone would work and drove home. No issues so far, no MIL, no rough idle, no hesitation (fingers crossed).
When I called the stearleship - they recommended I have the car towed, but would not speculate as to what the flashing MIL could be (catalytic converter or bad coil pack(s))...

So my 2001 5.3L truck has 206,648 miles on it. Over the years, it's been serviced every 5K with the only big repair being head gaskets which were done about a year ago.
Two weeks ago, I hit the gas to merge into traffic and the SES light started flashing and I could tell there was a miss. I got off the gas and a few moments later, the light went out and the miss was gone. I pulled the code and it was P0303 so I change the plugs, wires, and the coil pack for Cyl 3 fuel filter and ran a double dose of Sea Foam through the gas tank.
Bad news is I still have the problem. The truck drives fine; in fact, I pulled my bass boat 75 mile round trip yesterday. Everything is OK till you hit the gas hard to merge or to go up a big hill or pass someone. When you hit the gas hard, SES starts flashing and there is a miss. I also noticed the valves ping loudly when the SES is flashing. The only code it's giving me is P0303.
Could this be a bad injector not delivering enough fuel at higher RPM/under load? I was going to swap injectors and see if the miss moves. Any tips on popping those injectors out?

Was driving to Airport yesterday and out of nowhere got the flashing check engine and shudder/limp mode while trying to merge/accelerate onto the onramp (had to gun it to go around someone who decided to stop on the onramp for no reason). Let off the gas and the blinking went away. Upon leaving the airport I was accelerating again at highway speed to pass and got the blinking light and then a solid CEL. Found my way to a Autozone and got the code read. P0301 Cylinder#1 Misfire. Was suggested to change COP and plug.
Changed COP on the spot and had to drive it home to my tools to install plug. Thought maybe that since the CEL was still on solid after changing that the code needed to be cleared for the PCM to function normally again. Still have shudder when accelerating hard, so thought it might have been injectors so got cleaning service done at Goodyear. Still have the issue. Disconnected battery and performed IDLE relearn just now and it still is shuddering upon hard acceleration. Stumbled across TSB 12-6-4 which speaks to my symptoms.......I do not have the plate which in turn would imply I do not have the PCM update it references.
I have not noticed a misfire nor had an acceleration issue before so this was a surprise to come out of nowhere. I'm going to be calling my dealership in the morning.

So i got a 98 passat sedan used and was told it read a p0411 code. The person at autozone told him it was a cam sensor. The sensor was replaced. I know now from the manual that codes reads for sec. Air injection system , incorrect flow. It could be the vacuum lines. Now lets say it is the vacuum lines. Their is a misfire on cylinders 1-3.

I have a 2005 F-150 5.4L 2WD 90K miles. I started getting a misfire and hard jerk when going uphill. No codes for a few days but misfire got a little worse and more jerking at full throttle acceleration or level throttle up a hill got codes p0300 and p0171. I replaced the fuel filter cleaned MAF and changed plugs Motorcraft plugs (none of them broke during replacement). Miss got worse. Missing at idle and no power 3K rmp to get to 40. Only code pulled was p0171. Replaced upstream O2 sensors and COPs. Will barely idle now. Dies when put in gear. Full throttle barely moves forward a few feet just sputters. Checked vacuum lines cannot find anything. Only code I get is P0171. Fuel injectors next? Or shop?

I've got two error codes that are persistent. The underboost code will be fixed (I HOPE) when I replace the diverter valve which is currently sitting in my trunk.
But I'm getting a persistently intermittent P0303.
Here's whats going on:
-Some mornings, I can start the car and get a very minor rough idle, it seems to miss very occasionally.
-Some mornings, PERFECT Idle.
-Some mornings, Flashing CEL, very rough idle, P0303.
It seems to go away after about 30 seconds to a minute regardless. Sometimes ver minor rough idle comes back on hot start, but not enough to set a code.
What I've done:
-Replace spark plugs. (all 4)
-Replace offending coil with brand new one.
Still having the same issues!
Can these two codes be related, and once I replace the diverter valve, things will be better?

Went to do a few things this morning, started the car and it ran like crap. It was an obvious multi cylinder misfire. I checked to make sure all the coil connections and all other visible connectors were tight. Went back around and noticed the mil was flashing, so I shut it down and took the girl's car. I returned later in the afternoon and swapped out my intake in anticipation of it going to the dealer. Started up the car afterward and it ran fine without the mil lit. I had the codes pulled:
p0300 p0303 p0306 Its kind of weird that 2 coils would go at the same time. Do these cylinders share a coil or fuel injector driver off the ecm?

My wife's 03 Passat w/ 1.8t is bucking and lurching throwing a P0301 (Cyl 1 misfire) code. We have about 58k on the engine and had the dealer do the 40k service 2 years ago.
So far I replaced cyl 1 spark plug, swapped and then replace coil pack with new. My choices for parts were limited on a Friday night and these are el cheapo Autozone parts. Still missing and throwing DTC, I don't really have access to Vag-Com anymore (just OBD reader at parts store) and I don't have a Bentley's either (I know there's some eye rolling going on now).
How to troubleshoot the cause so I can make a decision to take to mechanic or do a few more parts swaps between now and Monday. I've got tools and a multi-meter. I used to have Vag-Com but it isn't supported on my new laptop (Vista), I tried the USB extension cord on my desktop but it is hit and miss.

The car doesn't seem to run that rough.
Replaced coil pack and spark plug wires with parts from O'reilly auto
16684 - Random/multiple cylinder misfire detected

I have a 99 Volkswagen Passat 1.8 Turbo Automatic AEB engine. I recently did a rebuild on it and ever since I keep getting this code P0301 that says "cylinder 1 misfire". The engine is also running rich and the spark plug in cylinder 1 keeps getting gummed up. I've changed the coil and the spark plugs and the injectors and it works temporarily but then the problem keeps reoccurring.

My son just left. We scanned his truck and got these codes.
P0172 Bank 1 rich P0300 random misfires P0303 cylinder 3 misfires.
I used the Torque APP Pro to check these codes. I went to live readings in the Torque APP and saw some readings for Long term and Short term bank 1 Readings.
They are all "greek" to me, and I don't recall what they were, but could get those readings tomorrow.
When I have done searches combining these codes together, I see changing spark plugs. P0172 alone gets me a different train of thought. Mainly CAT issues.
Also, his cranking to start is quite long. (A lot longer than my 6.0L would ever think of cranking) At least nearly 30 seconds of cranking. We are leaning toward first just changing #3 plug.

My wife started our '99 Explorer last week and she said that the engine was rattling. I started it up when I got home and it sounded like something had let loose in the engine. We took it a local mechanic and he basically said that the motor was shot. I pulled the codes and it doesn't look good to me but I'm not a mechanic. Codes are:
P0301
P0302
P0303
P0173

My 2004 Cadillac CTS 3.6L started running rough, check engine light flashed on and off. Codes P0300 and P0303. The car has about 119000 miles. Could this just be the plugs? The car has been running fine up to today.

Just got a 98 f150 w/ 5.4 4x4 excab. It idles fine but under light accleration. It starts bucking and missing bad, if I step on it, it down shifts and accelerates fine. If I try to maintain one speed it misses bad. It is not throwing any codes right now. The check engine light did come on for like a minute but went back off before I could have it read. I hooked up a scanner just to see if any codes were stored and got p0300 and p0301. I am going to clean the MAF and check for vacuum leaks. I hear the rear plug and coils can get water in them causing similar problems.

I have a small problem that has been going on for about the last 6 months. It only appears once in a while, and only when I have parked facing uphill for longer than a day or so. Upon first start (cold) after sitting pointed uphill for a day or two, it starts real rough and sputters a bit. Then when I check codes, I always have a pending P0316 (misfire within the first 1000 revolutions) along with a P0306 or P0301. No dash lights or anything.
Since those two cylinders are at the front of the motor, could it be that the fuel is leaking back down the rail and leaving those two injectors dry? It isn't always both cylinders, sometimes one or the other. If this is the sign of something bigger on the horizon, I would like to have a heads up.

Alright so my car is popping up 4 codes.
P0411 - Secondary Air Injection System Incorrect Flow Detected
P0300 - Random/Multiple Cylinder Misfire Detected
P0302 - Cylinder 2 Misfire Detected
P0303 - Cylinder 3 Misfire Detected
Vehicle: 1999.5 VW Jetta MK4 2.0L GLS (AEG)
The P0411 code I have had for a while now and I been lacking to fix it. I pretty sure I can get this fixed but it doesn't cause problems so I haven't paid to much attention to it. Anyways, the other day I noticed a puddle of coolant under my car so after checking it out, the water pump was leaking so I bought a new one and replaced the old one. However, during the replacement process I had to remove the timing belt and I accidentally turned the top pulley about 1 notch and didn't notice at the time. After putting everything back on, I turned my car on and the engine sound a bit weak so I ran for about 10 minutes around a couple blocks.
I instantly noticed that the car had no power and it took me a long time to speed up. When I got back, I plugged in my scanner and I only had the same P0411 code and nothing else. After carefully reviewing the camera I had recording during the water pump replacement, I notice I had turned the top pulley a bit so I went ahead and removed the timing belt, readjusted it, and it worked! I was excited that the car was working fine again. Soon after, I headed out to take a drive and noticed after 60MPH the car didn't have much power. The car still accelerates after 60MPH, but extremely slow. As soon as I arrived back home, I plugged in my scanner and that is where I seen the 4 codes. Now my question is what could have caused this? Could I have damaged something when I ran my car with the incorrect timing?
Things I have done so far:
-I checked to see if I left anything unplugged.
-I checked for any vacuum leaks
-I checked my oxygen sensors so see if I was running rich/lean
Things I will do after work today:
-Check the spark plugs
-Check spark plug cable for damage
