Volvo :: Idling High (1500 RPM And Higher) And Throwing 7 Codes
Dec 15, 2012
The car is a 1994 volvo 960, it has a rough idle, and its idling high (1500 rpm and higher) its throwing 7 codes, we just replaced the O2 sensor, we reset the computer, and still have issues, (though its no longer running rich!!!)
Here are the codes
1-1-3 injector group 1
1-1-5 injector group 2
2-1-2 O2 signal
2-3-2 long term fuel trip idle
2-1-4 rpm signal
3-1-4 cmp signal
2-3-3 long term ilde air trim
We also checked the idle control valve points 1-2 read 15 ohms and specs say 10-14, for the harness side port 1 read battery voltage (12.3) and port 2 initially read 10.2 then we wiggled and played with the injector wiring harness and it read 11.8.
We also poured fuel system cleaner right into the fuel filter and started it up, and just dumped the rest in the tank
I'm heading out to check those other sensors but what else could be causing these issues, also the temp gauge is reading cold all the time, but the fan kicks on when the car gets warm.

Sometimes I will stop at a light and my idling rpm will go from 600 (usual rate she idles at) to about 950. While this may seem inconsequential in the grand scheme of things, it's noticeable enough that it seems like the car wants to go. It'll lead me to depress the brake more. You can also hear the higher pitch of the faster turning engine (it is a 50% increase in speed). This will happen at random times so I have not been able to pinpoint if it is caused by a particular driving style. ECM for this?

I just has a gen 2 haldex and wireless controller installed. 10 minutes of driving around getting on it in sport mode, I feel a thunk from the back and when slowing down a few odd shudders. Drove it cautiously a bit more and felt fine, then harder and harder. Felt better, no understeer, seemed ok.
Got home and scanned with Vagcom, got the errors below, cleared DTC and scanned again, same errors.

I recently had an issue with a coolant leak. the Y shaped coolant line connection went bad located under the power steering reservoir. The car got hot and the coolant light came on i immediately turned the car off and saw coolant leaking out from this.
Now today I start my car it has a rough idle and dies once it dies it doesn't start again and the epic light comes on throwing the codes

17951 P1543 Throttle Actuation Potentiometer Signal too Low

Throwing 2 codes -
P0172: too rich
P1176: post cat 02 reached limit
Last time it turned on it had horrible air flow, it felt as though it was choking. definitely not a misfire. occasionally after spirited driving the engine would die after I came to a complete stop then worsened to cutting off when I put the clutch in at high rpms. also have a slight loss of power. I also recently added a 3" tbe and changed coil packs.

My girlfriend has a 2000 B5 and it's been throwing a p1136 (Fuel trim too lean: probably a vacuum leak) and p1113 (B1, S1, pre-cat O2 sensor) for about two weeks now. How long can she feasibly leave this stuff before doing any real damage?
I just don't have time to check her manifold for vacuum leaks for at least a few months (summer) or deal with the O2 sensor. I mean she doesn't need to get it inspected until Nov 2007, so, all she has to put up with is that really annoying beeping and "emissions workshop" lightshow every time she starts her car up.

So my car has been dropping multiple codes after I scanned her and found all five: p0303, p1128, p0172, p1300, p0301. She is just a simple five speed AEG and has no mods other than a SRI. I already replaced the MAF but that ended up causing more codes and I have checked the vacuum lines to no avail.

So recently I took my engine apart to do a valve cover gasket and Ecs tuning 2.0 coil conversion. I noticed a good amount of oil in the plug tubes so I got out my trusty soap dispenser and started pumping out oil. Pulled plugs and cleaned them (wanted to make sure oil was all out b4 getting new) also while I had it apart I wanted to take intake off, ( just to polish it and clean out any carbon inside).. Well I never ended up doing that. I removed the injector connections and realized it was to much work for such little satisfaction. So I plugged the injectors back in.
I got my car all back together and now I'm throwing 6 cel codes!! P0102 (maf) which I'm assuming b.c I took it off for so long, p0201, p0202 ( injector 1 and 2 miss), then some misfire codes p0300 (random) p0301 (cylinder 1) and p0304 (cylinder 4). The car starts runs very rough then cel comes on and blinks. I was thinking maybe the oil getting down to the combustion chamber couldn't be the best for it but it would just burn off. Only other thing I did was take off the thottle body and cleaned it.

I have had a wet weather issue twice, once last fall and once this spring. Both times were very wet and damp conditions causing a sputtering and chugging and dying at lights, both times no codes and after drying out in brother's shop it went away. Now this weekend up at the cabin it reappeared, again very wet conditions. Replaced the MAF...no change. Sputtered and chugged my way home with it killing at most stop signs/lights. Finally got home and couldn't even back the TT up the driveway, it would kill. Finally threw numerous codes (misfire in cylinders 1 and 9, and misfire in first 1000 revolutions). I'm thinking COPs as the plugs are not that old and the little research I have had time to do suggests this also. If it is COPs, I have heard there are some to avoid and some that are recommended?

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
P0300 - 35 -10 - Intermittent
16686 - Cylinder 2
P0302 - 35 - 10 - misfire detected - intermittent
16687 - Cylinder 3
P0303 - 35 - 10 - misfire detected - intermittent
I have searched and browsed multiple websites and threads to no avail. They all seem to be dead ends.

So my girlfriends's 2001 2.0 Golf (engine code AVH, 153k miles) began throwing codes for misfire on cylinder 4 and for the o2 sensor (post-cat) recently. I went ahead and replaced the spark plugs, wireset, and the coil pack. They were way overdue. The CEL went away for like 30 miles, and then came back. Now it's reading misfire on cylinder 3 and the same thing for the o2 sensor. What else it could be? Search is coming up blank, most people replaced the coil pack and the CEL went away.

I have an '05 5.4L 3V and I was way to trusting in how it was running. BTW, I change the oil every 3 to 5 and have only driven highway miles, albeit a lot of them...155k! I bought it with 40k on it but was not aware of the plug change issue until I heard about it off-hand. I let the plug change go cuz it was running so well. Bad move.
Anyways, a few weeks ago it began to lose power and I suspected that the PCM was retarding the timing for some reason. Before I could get to the shop, the thing went nuts on me at 75mph. Started shaking and sputtering and throwing cel codes. I shut it down and after 5 minutes re-started. It seemed fine and actually was running a bit better. Took it in and the code was the 0302. #2 cyl misfire.
They also said the compression was very low on that cylinder and slightly low on 1,3 and 7 as well. I had them change the plugs and the #2 COP even though they said I needed a new engine and then I picked it up. Now the engine barely runs at all. It shakes violently, where to go from here. What should I do now? New engine?

My trucks throwing 2 codes after traveling at low speeds and getting pretty warm. Drove it home after it cooled down. P1451 with is the EVAP Cannister Vent solenoid and P0353 which is Cylinder 3 Primary/Secondary Ckt. I keep getting told these are not connected but im not sure I believe that. Ive replaced the coil with 2 of my stock coils already with no luck, ive replaced the spark plug as well.

Any LED I can throw in the footwells / license plate area that won't throw a code? I'm using the ones from superbrightleds.
They worked everywhere except the license plate and the footwells. Everytime I get in my car I have to see (check license plate lights!) and a bulb out icon.

Recently bought 98 f150 xlt 3 door 5speed 4x4 4.6l 230k miles for $1k was throwing misfire codes on 1,8,4,3 cylinders. Usually throws two cylinders at a time and never the same cylinders consecutively
Parts replaced:
coils...msd blaster
belden wire
motorcraft plugs...when i did these it ran perfect for a tank of fuel...18mpg no stumble
two cans seafoam through the tank
tank was dropped and drained
fuel filter
one can seafoam intake cleaner
3" exhaust from the Y pipe back
MAF cleaned
Previous owner said to have tested and cleaned injectors but I am not positive it was done... I don't think its mechanical because it wanders through the cylinders and when i changed the plugs it ran spot on. it gets worse the warmer the truck gets also.
injectors?
clogged small cats?
sensor?

I have a 2006 Lincoln Mark LT that seems to have an intermittent misfire. The truck is not throwing any codes either.

So I just had both cats replaced and now the car is running very rough and trowing out mis-fire codes. What could cause this? Going to disconnect the battery to reset the computer to see if that might work.

Currently throwing both P0441 and P2096, just prior to this I was also throwing P0442.
Read around on web and decided the simplest thing it could be would be the fuel cap, may as well start there. Owners manual even recommends changing at 90k. Got a replacement from advanced (which is supposed to be built to OEM specs), re-set battery light stayed off, attempted to pass emissions but a few systems were "not ready". Was good for 80ish miles. Light came back on throwing P0441 and P2096. I re-tightened fuel cap and re-set battery, light went off.
Did some maintenance; spark plugs, air filter, oil/filter change and replaced the leaky oil pan. Keep putting on miles hoping to get to the recommended 200 mile mark before stopping by the emissions testing facility, 105 miles after re-set same codes came back. I'm almost positive I replaced a o2 sensor 2ish years ago for emissions. Also there is an obvious exhaust leak which could be a culprit. I seem to remember reading somewhere that a weak battery can cause problems with fuel pressure... not sure if it's true or not but for what it's worth I do know my battery is on it's last leg.
I'd like to avoid unnecessary fixes, it's only my winter car so as long as it's nothing major I'm not going to dump money in it. I'm going to take a guess and say the check engine light is coming on when these systems become ready. Plan is to try this re-set one more time hope for the best and if not replace exhaust or at least repair leak. Not sure on my next step for P0441 though. Vehicle is a 2004 Hyundai accent with 86k on it.

My 2002 Dodge Dakota Extended Cab pickup is throwing several different 02 sensor codes. The first one was P0132. I reset the CEL and it ran good for about 1800 miles (100,140) on the odometer now. Now I'm getting a P0158 code and CEL went off after a few miles. Now it's back to a P0135 and P0138 code. Are the 02 sensors really bad or is there an underlying problem with the wiring or the computer. The truck runs like new when the CEL is off. The P0132 has never shown up again. The engine is the 3.9 V6 and is 2WD.

so i bought this truck about 3 months ago and it was running real bad when i got it, I went ahead and changed the lower and upper intake gaskets, cleaned throttle body, egr ports on lower and upper intake, did timing chain cover gaskets and 3 bad injectors i found while doing gaskets, truck ran better but still black smoking(running rich) and getting 8 mpg. So I changed fan clutch,fuel pump fuel filter,airfilter,MAF sensor(old one was pulling 14.4 volt), DPFE sensor and all 4 oxygen sensors(old ones carboned up and real sooty).
I've checked my egr valve while idling and when it opens the engine just about stalls, truck seems to be running better but CEL light came on again and is throwing these CODES:
P0453 (evap emission ctrl sys pressure sensor high input),
P0141,
P0153,
P0135(oxy sensors),
P0401exhaust gas recirculation flow insuff detected,
P0460fuel tank level indicator circuit error.
And I believe I've told everything i know ...
