I have a 2009 Corolla with a 1.8 L. I have the misfire code P0301. I have changed the plugs, ignition coil, and fuel injector on cylinder one. It still has the misfire.

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?
2009 1.8 Corolla . I'm chasing an intermittent P0352 code and misfire. Code points to coil pack #2 . Question is, which one is #2 ? I want to swap coils and see if the error follows the coil but I can figure out which cylinder is #2 and since all of the coil wires disappear into a loom, I'm not sure how else to tell.
View 2 RepliesI have a 2009 Corolla S 1.8 with a manual transmission and 30,000 miles. About a month ago the check engine light came on throwing a PO302 code (cylinder 2 misfire detected). I reset the check engine light and drove it about a week before the check engine light reappeared again with the PO302 code. I swapped the spark plugs on cylinders 2 and 3 and reset the check engine light, the PO302 soon reappeared. I swapped the coils on cylinders 2 and 4, and reset the check engine light, the PO302 soon reappeared. I swapped the fuel injectors on cylinders 2 and 3, and reset the check engine light, the PO302 soon reappeared.
View 1 RepliesI have a 2010 Corolla S with 130k miles and started developing what felt like a slight misfire at idle. Dealer suggested change the plugs and if not that try the coils. So I got the wrong plugs givin to me there 5/8s not 14mm. I found a socket that worked and thought the old ones where the same as the new ones.
The 5/8 socket fell right in and knew it wasn't the right size after the plug wasn't tuning. Then I searched and found out there 14mm plugs. So now the socket is stuck inside the metal tube that goes into the head. I tried a locking extensions, long needle nose, hook with a slide hammer, pb blaster, heat, crc freeze off. Even tried spinning it as pulling up with an impact.
A couple weeks ago, my check engine light popped on and I noticed my engine misfire. I happened to be driving by an autozone, so I pulled in and had them check the code. Came back as a misfire on cylinder 4, possibly bad ignition coil or clogged injector. I ran some techron for the next couple of gas tanks, didn't seem to do much, as I would still occasionally get the check engine light.
It has been getting more and more common for it to happen while driving since. Today on the way home from work, it misfired several times in a row and got so bad that I couldn't get above 40mph. This lasted for a minute or two, then cleared up and I made it home without a hitch. Took it back to autozone, same code..Cylinder 4 misfire, probably ignition coil or primary/secondary ignition b fault. I went ahead and bought an ignition coil, came back home and installed. Just took it for a test drive and now I've got the same issue.
I only replaced the one coil that has been throwing a code as misfiring. I did not also replace the spark plug on that cylinder.
My Corolla has the P0441 code, but not the typical 0445 code that comes with a loose gas cap. I cleared it and it came back (yes, I checked the gas cap). Googling the issue, I found service bulletin SB 0392-08, which implies the ECM could need to be replaced if the issue is not in the Evap system.
View 1 RepliesI have a 2009 corolla LE with 81,000 miles on it. Today after I got gas, the check engine light came on. I checked the OBD code and it said P0607. I cleared the code and continued to drive it and it ran fine and the light has not came back on yet. I'm a little worried about driving it on long trips now.
View 2 RepliesI have the code P0500 on my 2009 Matrix. The odometer doesn't function, all error lights are on, the power steering is not completely out but it's reduced. Also, the rear windshield wiper is constantly on. I replaced the vehicle transmission sensor today because I thought that would fix it all. It had absolutely no effect.

When i erase it comes right back!
Open in (D) Squib Circuit. What to start looking for?
'07 Avalon with 169k miles. I replaced all 3 back coils and 6 plugs back in December when I had various misfires, but the most common code was P0301 which is cylinder 1.
Car ran great until last week when I made a hard left and accelerated. CEL started flashing, read code and it's P0301. Every time I accelerate half throttle or more I can set the code off, but then shutting down car and restarting it drives fine, until I go half throttle. Car runs better when cold, and worse when I turn left and accelerate.
As long as I don't mash the gas I can drive for a half hour or so without the strumbling/hesitation. Surely the new coil hasn't failed so soon, I hate to pull the wipers, plenum,etc. and buy another coil just on a chance that might solve the issue. Car is only throwing a P0301 this time, no other codes like before. I've read a clogged cat or sticky exhaust valve could cause a cyl misfire.
My 97 F150 through a CEL Tuesday night P0301 so I picked up a new plug because it's cheap and simple, but that didn't do anything. Spark plug wires are about 3 months old, I also swapped injectors between 1 and 2, and misfire stayed with cylinder 1. It also gained a tap when the misfire started but only above idle, but it doesn't sound like a rod knock.
I also noticed if you unplug injector 1at idle it taps/knocks 3 or 4 times, however if you unplug any of the others it doesn't do that. I checked and I definitely have good spark from the plug. I plan on picking up a new compression tester tomorrow since mine never was returned. If you take the oil fill cap off it doesn't have any blow by at idle, however if you rev it you get a quick cloud out of it.
I thought about picking up a kit to check the injector pulse.
This happened xmas shopping with the wife. Started misfiring on the highway,took the 1st exit to find a garage as I am 20kms from home. The vibrations were worse at stop, but made it to a garage. They gave me the p0301 misfire cylinder 1, said they don't touch 5.4 plugs, told me to go to ford 2kms down the road. NICE. 4 in the pm, FORD dealer worse case scenario. Nope gave me a loaner told me come back at 930am. Truck was just waiting for an injector when I arrived. Plug & coil were good injector was shot,changed the fuel filter & oil change.
View 6 RepliesI have a 2009 Corolla S w/ 79K miles on it and recently my check engine light came on with the trouble code P0352. The engine would misfire while accelerating and then was extremely rough when at a stop light. This issue and check engine light have been happening intermittently over the last few days. I don't really know anything about engines/cars but doing some research came back with the following...
Possible causes
- Faulty Ignition Coil 2
- Ignition Coil 2 harness is open or shorted
- Ignition Coil 2 circuit poor electrical connection
- Faulty Engine Control Module (ECM)
Basically my question is how do I troubleshoot and figure out what the real problem is? I would rather not buy and replace the Ignition Coil if it is something else. From everything I have seen it seems the simplest method to test the coil is to switch out the ignition coil and spark plug on coil 2 with one of the other 3 ignition coils and see if the the trouble code follows it or stays on 2.
About 2 months ago I started having a problem starting my car. It would crank and crank but wouldn't start. Eventually it would start but threw a code for the camshaft position sensor. I figured I'd go ahead and replaced it. Still had the same issue after about a week without problems, except this time the crankshaft position sensor code.
I maintain my car very well, and it just recently passed 45k miles. It's a 2010 Corolla S.
The check engine light on my 09 Corolla came on so, after it continuing to stay on, I bought a OBD ll Code Reader. The scan showed 10 faults but, only 3 code numbers were given for the 10 faults. Each of the 3 code numbers appeared twice for a total of 6 out of the 10 faults indicated. The remaining 4 faults had no corresponding code numbers. Don't know why but, they just didn't. Even after multiple scans.
Here are the code numbers that did show.
P2401(twice)
P2402(twice)
P2419(twice)
According to the CD that came with the reader, this is what the codes mean.
P2401.. evap emission system leak detection pump control circuit low.
P2402.. same thing as above except control circuit high.
P2419.. evap emission system switching valve control circuit low.
Looking for more specific explanation to me what this all means then it has something to do with emissions. Is it something that should be of concerned? I have erased the codes a couple of times but after a day or two, the engine light comes on again. This has been going on for over a month now but, the car is working great. Last road trip, I got approx 52 mpg.
My friend was told by Toyota that the Air Fuel Sensor code was the reason why her 2010 Corolla VSC and engine lights were on. This was after she visited her mechanic who changed the O2 sensor.
Is there a way to change the Air fuel sensor herself without having to pay Toyota...
I have a 2009 Toyota Corolla (It has a 1ZZFE engine). The car for a long time was a little problem when starting (long cranks and several tries before starting, but no check engine light at all), then, after adjusting the PVC hose for 3 days the car worked perfectly, but one week ago, in the morning when trying starting, it was impossible. I scanned and got a U0100 code, tested crankshaft position sensor and it is ok, tried with the other key but same result, only cranks, no start at all. After scanning, it started briefly and suddenly went off, tried again, and only cranks.
View 1 RepliesMy 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.
So I dropped my prius off to get looked at for error code p0301 number 1 cylinder missfire. They ruled out Spark plugs, coils and fuel injector. What else is ther? Also could it be the battery or even gas?
View 12 RepliesI had a consistent misfire on this car and finally got a P0301 trouble code. I installed new Autolite AP 104 plugs and wires. Now, when I start the engine. it runs perfectly. But when I put it in gear, it misfires. After a minute or so, the misfire clears and the engine runs perfectly. I have not received another trouble code. One thing I did notice is that the plugs I took out (Motorcraft AWSF 32P) had a much larger gap than the .044 the associate at AutoZone set the new plugs to.
