Saab - 9-2x :: 2005 - Misfiring On Cylinders 2 And 4
My 9-2 is misfiring on cylinders 2 and 4. At first we suspected a timing issue but that doesn't appear to be the case. My mechanic is looking at it but can't seem to locate the problem... so far:
- replaced old spark plugs
- checked the coils (moved them to see if the misfiring followed the coils--it did not)
- checked the timing belt (all good)
- compression is good
- fuel coming in is rich
He's dropping the exhaust today to check things from that end... A faulty mass airflow sensor wouldn't effect specific cylinders would it? and we'd see a degradation in the fuel richness right?
Avalon 2005-12 :: Engine Misfire On All Cylinders - Coil Code P0356
What to do Misfire Error all cylinders also coil code P0356 . It is 2006 Avalon Ltd with 37,000 miles always maintained and all recalls completed. Is there something I missed or is this for real or could there be a common problem that is causing all the errors. Car idles ok and no problem driving below 60 mph anything over and you can fell a shutter like it will lose power.

How it all got started: [URL] .... Replaced Check Valve (06A 133 528 D/A) today, car is still idling rough, flashing CEL but it's solid/no CEL when the car is moving.
What I have done so far:
1. Replaced Turbo Inlet Pipe (Cracked at one corner)
2. Replaced D.V. (Original was fine)
4. Did Smoke Test, No Vacuum Leak
3. Replace Check Valve (06A 133 528 D/A) Above The Intake Manifold
4. Cleaned Throttle Body and All Pipes under Intake Manifold
Codes keep reappearing:
17705 - Pressure Drop between Turbo and Throttle Valve (check D.V.!)
P1297 - 001 - Upper Limit Exceeded
And All Cylinders Misfire
Car idles fine when I squeeze this hose marked in green : [URL] ....
Something I noticed before and I think it's still doing it, there is weird noise every time I shift to reverse or drive, It sounds like when you just open drivers door.

View 2 RepliesGolf/GTI VI :: Cylinders Misfiring Lost Acceleration
So last night i was driving and i made a turn onto the highway and speed up to pass this slow ass car :thumb down: and as i did i lost acceleration and my car started to rumble like when you use a high gear when u make a turn while moving that slow acceleration. And as that happened my engine light turned on and my EPC so i drove it well barely made it home. i had a friend with his VAGCOM come to see whats wrong it said cylinder 1&3 are miss firing so he took his ignition coils out of his car swapped them in my car and we drove it around and it drove fine and no fault codes. so now my issue since i have GIAC, CAI and APR full exhaust if my warranty will cover to have them put new ignition coils since i did get an extended warranty. I'm just afraid they won't.

Is it possible that disconnecting battery causes a misaligned throttle body, which in turn causes the EPC light to come on? And does a misaligned throttle body also cause misfiring cylinders (1 & 2 in this case)?

A couple of months ago I replaced my coils because of misfires. Just yesterday I satarted getting the running in 3 cylinders feeling. So I was woundering why they went out so fast? (Coils were from my brothers 20th gti)

2000 Excursion V10.
Recently cylinders 1,2,3,4 wend dead on my wife's Excursion. I searched here for a pin out diagram so I can check all the wires from the coils to the PCM. I changed the coils on those 4 cylinders with no change and then swapped them with the coils on the left side of the engine. the problem stays on those 4 cylinders. Any link to pin out the wire harness for the coils to the PCM
Golf IV / Jetta IV :: 2004 - All 4 Cylinders Misfiring Randomly
So I have a 2004 jetta GLI (1.8T) with forge splitter valve and short ram intake. I went and got my codes pulled and all 4 cylinders misfiring and random misfires. I replaced both coil packs and spark plugs. check engine light popped up again after about 20 miles and same thing. I just bought the car so I'm not sure how long it has been running with these misfires. I just got the timing belt replaced. I know it could be off a tooth. (Wouldn't a code pop up though for it?) How could I check that. And I also took my MAF sensor off as well and no change. Heard it could be clogged cat, any way to check? I've also cleaned the throttle body. It runs fine when I'm driving, just a rough idle.

My friend has 2000 12v vr6 auto and recently he experienced his car bogging under acceleration. He had the plugs and wires recently done to solve the problem and the problem went away for a day and has since returned. I scanned it and here are the codes that its threw. After doing some research i'm thinking its the coil pack, since it was pretty foggy/damp today (when the problem started again).

Accent MC (2006-11) :: Low Acceleration And Engine Shaking / Two Cylinders Misfiring
So as I was heading out the other day, the car had low acceleration and engine shaking. The check engine light started flashing.
Checked the codes at the parts store: P0300, P0301, P0303.
I just dropped it off at the auto repair shop.
Could it be a I'm just wondering if I shouldn't have taken it to the dealer as the printout says it could be a CPU issue?
Hyundai - Accent :: Multiple Misfiring - Operating Stuck On 3 Cylinders
So my 2008 accent is my daily driver. I'm nearing the 300,000 mile mark but the last 100,000 miles have been plagued with random multiple misfires. I have changed the cables, crankshaft sensor, plugs, and I've been through numerous costly coils (I keep 4 with me). All listed parts were most recently changed at the same time. Why do I misfire on nearly every commute and get stuck operating on 3 cylinders?

97 F150 4x4 XLT 5.4L... I had two cylinders misfiring, removed COP, injectors and plugs. Reinstalled all parts and reconnected all sensors. Now I am not getting fuel to the injectors. Double checked for disconnected wires and hoses, checked all fuses and relays, also the inertia switch. Fuel pump does not hum when key turned on. Tried hitting bottom of gas tank. My question is, before I pull the tank again, is there something under the hood I may be missing. It does get quite crowded at the rear of the motor.
View 6 RepliesGolf IV / Jetta IV :: 2001 VR6 GTI - Idles On 3 Or 4 Cylinders / Runs Rough
2001 VR6 GTI....
Already done:
Replaced the coil pack and plugs
Measured resistance of plug wires (all at about 6K Ohm)
Replaced front O2 sensor
Replaced purge solenoid valve
Replaced coolant temp sensor
Replaced fuel filter
Replaced fuel pressure regulator
Replaced MAF sensor
Cleaned the throttle body
Cleaned the throttle position sensor
Ran a tank of seafoam treatment (injectors were new 6 mos ago.)
Checked running voltage of battery
It was smoking and stinking bad with a rich mixture. It improved with the MAF change but still runs like a farm tractor. Now it idles on 3 or 4 cylinders, runs rough through 3000 RPM then runs cleaner at above 3000 RPM, but only at light throttle. CEL is either on or flashing when driving.
Don't know what to do next - nice car not fun to drive like this. What this could be and how to test it?
Ford 6.7L Power Stroke Diesel :: 2014 F350 - Two Cylinders Misfiring
2014 F350 6.7... The truck has only 30000 miles on it. I was driving uphill and the engine just quit, but fired up right away after with engine check. On idling run at 500-700 rpm , no power, clicking noise , sometimes shaking. Took to the closest dealer right away, they don't know what is it, but they want to rake of the engine . This truck is not under any warranty. This is my first diesel truck, didn't expect anything like this....
View 4 RepliesFord Super Duty (1999-2016) :: F250 V10 - 2 Misfiring Cylinders
I just bought a 99 F250 Super Duty with the V10. When I bought it, I knew it had 2 misfiring cylinders (4 and 10) because it was throwing P0304 and P0310 (only 2 codes), but wasn't concerned as I've had to take care of my wife's Escape with it's misfiring cylinders. I replaced the 2 coils and replaced the plugs with Motorcraft plugs from O'Reilly's, cleared the codes and she ran fine for a couple of days. Now I'm getting an intermittent misfire, it's only occasionally throwing a pending code of P0300 which is "Multiple Random Misfire".
I'm fairly certain it's an issue on the electrical side because if it were an issue with the injector or injectors it would be constant regardless of RPM... right? As it is now, it basically does it between 55-65 while in overdrive trying to pull a hill or slightly accelerate. Once it's shifted out and the RPMs go up to 2k+ it runs like a champ... and it kills my fuel economy. The way it's behaving is just like when a coil is bad, but it's saying it's not identifying a specific cylinder (saying it's multiple) and it doesn't always do it (about 60% of the time).
I checked the MAF and it's very clean (looks almost new), checked the vacuum lines (those I found without a manual) and couldn't find any leaks and when I changed the plugs all the plug wells were dry.
Ford Super Duty (1999-2016) :: 2011- Misfiring On All Cylinders?
SO this truck came into the shop yesterday with a really bad misfire. pulled the codes and got a misfire codes for cylinders 1-6 and also p1450 (unable to bleed fuel tank vacuum) and p068a (pcm/ecm power relay de-energized too early) i found a TSB related to the issue, TSB 10-25-7 i did as the tsb told me to do and pulled valve covers to check out the rocker shaft rollers and inspect for any signs of surface deformation or fatigue. they were fine on both sides.: ive got spark in all cylinders. fuel pressure was right around 55-60 the gauge was fluctuating pretty good. checked for bad fuel or water in fuel ect. fuel seems to be good. pulled O2s incase of plugged cats still ran like crap.

I have a 2009 f250 with 5.4l 3v. have had the truck only about 6 months. it started missing about a month after I got it. I replaced all 8 cops and all 8 sp. The truck ran excellent until 11/29, then I got a cel and the truck started running really bad. Found 3 misfiring cylinders. Changed all 3 cops again and that did nothing. Pulled the injectors and found 2 of them were clogged, replaced those also. Still no change was told by someone that the ecm/cpu may need to be reset, did that also. Still no change. There are no codes present but still has the multiple misfires.
