misfire

Ladies and Gents, I thought I would document this issue, as I researched a fair bit over the past 2 weeks and couldnt find this solution, however stumbled on the fix. Symptoms and Issues: I recently bought a WM (VE) Caprice 6 Litre v8, great car, but had a LOT of kms on the car. Found a few...

Hi i have been having problems with my 2006 VZ V6 ute (manual) 72,000ks I bought the car a few months ago, previous owner did sparkplugs, coilpack, service.. but the car would shake hard at idle and sounded like it had a slight miss randomly the check powertrain would pop up and make it run...

Hi All, My 2010 SV6 SiDi is throwing a P0008 code and a P0301 misfire code, and a P0087 (is this a fuel pressure issue?). They seem to be related as the car did not appear to have any issues prior to it going full limp mode on me today and is now showing both. However my research seems to...

I have a fault code coming up for Ignition Coil Cylinder 5 Circuit High Voltage(P2313). I have replaced the plugs and coils and checked the fuses but that hasn't fixed the problem, the misfire and code keep returning. Has anyone experienced this issue before and managed to resolve it, if so how...

Here we go again VY V6 2004 I replaced the LIM gaskets and water pump. After starting car it idles really rough as if it’s missing or vac leak. During the LIM gasket repair I removed the alternator and found the worst wiring job that goes to the alternator plug/reg. I cut and soldered similar...

Hey there, I’ve been having some issues with my VE omega, had a couple of people look at it and not seen anything particular with answers so looking for another opinion. The car is fitted with autogas, which seems to be causing the car to run rough when the gas is engaged. It only happens every...

HI, my 2013 sv6 ve is misfiring in the 4th cylinder. Only at idle, under load even the slightest amount it runs smoothly, I've swapped over sparks, and coils and attempted at an injector clean, any thoughts on what could be causing the issue? Wondering if low compression could cause idle...

Hi everyone, I've looked through previous posts and can't find a circumstance that lines up exactly with what I'm experiencing, at least in about half an hour of reading. Anyway, about 2 months ago my car started one time after about 100 km of highway driving and being left for 2 or so hours...

UPDATE SORRY! Since this time the engine in question had spun a bearing, however it did run good for a bit, the problem was bad fuel from some BP around SA. Youtube video to showcase the noise and trouble. Really not a huge amount of ideas left. This issue only became noticeable when i...

Hey everyone I've got a vs statesman series 2 97 model v6. I've got a bad misfire I've replaced plugs I've done the leads I've changed the coil packs twice. Done the plate once and it's still misfiring. I've heard it could be the crank angle sensor or the fuel pump/ filter. Has anyone had this...

Hi guys Over the past few weeks I've had a cold start misfire/rough idle start. I'll start it in the morning and it will cough and splutter it will Rev up and then idle and run perfect with no issues even if I turn off the car 2 min later starts fine. I've done all 3 coils, spark plugs and...

Hey guys, I recently rebuilt this engine with 280,000kms on the clock. Did a very quick/cheap job of it (This will teach me a lesson in not half-assing things). It idles/runs very nicely until it gets up to 100+km/h, when I occasionally get misfires down bank 1 and it's reporting the fuel is...

Hi, I have a VE SS 2011 series 2 manual with 171k kms ive had an issue twice now where upon starting my car will have a stability control fault and when i take off it seems to be misfiring aswell. I fixed it the first time by disconnecting the battery and waiting approximately half an hour and...

we have an 07 VE with 135,000km, battery died so I replaced it. Everything worked fine until the next day when it developed a bad misfire on cylinders 1,2,4 & 6. I replaced the coils and plugs and the misfire was still there but now cylinders 2 & 6. Disconnect the battery to see if that would...

Hi, I have a vz thunder S pac Ute 2006. Once you put any power into it the powertrain light comes on and engine light whole car shutters and have to turn the car off and on. Car will also constantly misfire. Had a mechanic look it over and check the codes only think that cane up was cylinder 6...

Hey guys, I was wondering if anybody would be able to help me understand some information i logged tonight. This log was taken over 50 minutes, 50/50 town driving around 30-50km and highway run 100km. HSV E2 Senator 6.2l ls3 317kw 6sp Auto. I recently bought a bluedriver obd2 tool which had...

Hi all, Can anyone throw their thoughts in on what my problem may be. My VX has been giving me a lot of greif lately, between trouble starting it to ruff idle, to just driving like rubbish in general at the moment. I took her into the mechanic and they replaced the crank angle sensor (seemed to...

Hey all, I'm after some advice or help in regards to my 2014 VF SV6 wagon. It's been off the road for 2 months now and honestly it's killing me! I've got some sort of problem with the engine where it has thrown a few coded at me, it idles extremely rough and is in a sort of limp mode, the left...

Hello. My VX SS has a terrible misfire with a rough idle that is throwing no codes. Here are a few things I've noticed. 1: car starts right up, so I don't think that the fuel pump is bad 2: when it's idling rough and I try to press on the pedal, sometimes a loud popping noise comes out of...

hi everyone, i have a really frustrating problem and i hope someone can help me out before i ust rip this engine out and put a new one in. i have an 04 vy s2 and it idles like crap. Its idling at 900rpm so thats not too bad but it is a bit shaky, then when you give the pedal a jab it misfires...

Hey guys, I’ve just finished converting my VZ Calais from V6 to V8, and it now has a miss on cylinders 2&3 under acceleration. Dash loom, engine loom, bcm, pcm, pim all replaced. Plugs, leads and coils have been changed, injectors have been checked. Happens around 1400RPM then smooths out...

Hey everyone, so after months of painful diagnostics I still haven't been able to source the misfiring problem on my VZ, after pretty much rebuilding the top half of the motor there's only a few plausible causes left and I was wondering if this would be one of them? Also curious that the last...

Hey guys iv got a vy v6 commodore that has had a miss for some time which i thought i had fixed, but i have noticed the miss comes back once the engine is hot. Originally i replaced coil packs, dfi module, plugs and leads and the car has been running great. I have recently got the car...

Hey guys. Just wondering what other causes of a bad misfire would be? Coil packs, spark plugs and leads have all been done correctly. The car tends to carry on and miss pretty bad when hitting 2500-3000rpm at 60-70km. Also idles pretty rough or while rolling. Can hear it in the exhaust but no...

I think I may need to change my injectors as my car has a huge shake when I started it this morning and I got a check powertrain error. I have a 2005 V6 VZ wagon LE0. What I Hector's do they have the blue or black. I have new plugs and could to go and just want to buy some reconditioned injectors

Have a bit of a misfire when accelerating. Usually happens when I hit about 2250-2500rpm at 60-70kms. Plugs, leads and coil packs have been replaced. Not really worried. But curious as to what else it could be if it's not coil packs?

Hey Folks, Seems i'm encountering an issue with my Vz (6 cylinder 175 kw), i'm getting a cylinder misfiring/locking out under very specific circumstances. On a cold start, car runs fine and will run fine indefinitely. However, do a trip and leave the car to rest for 10 minutes, turning on the...

Hi Guys, I have a 2009 SV6 SIDI (LLT engine). I occasionally get the P0300 & P0301 fault codes. Coupled with this I get a quite heavy misfire and smoke out of the exhaust, also a fuel smell when this happens. This issue is very random, might not happen for months and then all of a sudden will...

Hi First some background - bought the 2007 VZ wagon over a year ago - changed the timing chains and plug coils back then and has been good for 40K kms . Started getting check oil warnings a couple of months ago. Changed the oil sensor - warnings persisted. Fitted a cheap oil pressure gauge to...

Started my vz v6 lumina drove for a little bit, car started running very rough and misfiring. Checked all areas for vacuum leaks, there were non. One by one I disconnected the coil packs while the car was running and found that “cylinder 1” had no change when disconnected. I than swapped coil...

Ive just finished an l67 rebuild, Put new injectors in, new coils, tried multiple DFIs, new plugs and have tested my spark leads and, injector pulse, coil resistance and all. It goes pretty well when it goes but seems like it has a slight misfire. But when you turn it off and try to start it...

Kia ora, lads! I have a bit of a specific issue and I'm at a bit of a loss. For a while my VX supercharged V6 has had, on the rare occasion over the last few months, a guick misfire (by the feel of it) every once in a while. But today halfway home from work she decided to just run like a...

my 1995 VS Commodore V6 (Ecotec) started misfiring the other day ... I thought it was the fuel line which i cleaned out and changed the filter ..... nothing Then i changed all the spark plugs as the old ones were due to be done .....nothing i just swapped over the spark leads from my donor VS...
