Cooper Posted August 2, 2008 Share Posted August 2, 2008 The other day my car started to splutter while driving and i couldnt get power out of it to drive it up my street. So today i swapped over the fuel pump to a new walbro pump to see if thats was the problem but it hasnt fixed it. The car at idle is not stable at all it hunts and stalls if it isnt revved at all, it is also blowing some smoke aswell. I had the turbos replaced a couple of months ago and i havent had any problems until now. Does anyone have any idea what could be the problem because i really need my car running 100%.

Cooper Posted August 2, 2008 Author Share Posted August 2, 2008 Sorry i should have said its oil smoke it left oil residue on my shed floor Link to comment https://www.sau.com.au/forums/topic/230618-ruff-idle-car-blowing-smoke-what-could-be-the-problem/#findComment-4052290 Share on other sites More sharing options...
Pal Posted August 2, 2008 Share Posted August 2, 2008 (edited) try take if your cooler pipework, if there is oil one of them then one of your turbos is possibly stuffed. if not you need to do a compression test to see if it is your engine. i think each pot should be around 150 psi but not sure, anyone verify that?

Al Posted August 2, 2008 Share Posted August 2, 2008 Also check you AFM as a stuffed unit will cause the car to run in limp mode. The actual values of the compression test are not too important, AS LONG AS ALL 6 CYLINDERS HAVE SIMILAR FIGURES.

Cooper Posted August 3, 2008 Author Share Posted August 3, 2008 Any other ideas? It sounds like a tractor at the moment and isnt drivable at all.

QUICKY Posted August 3, 2008 Share Posted August 3, 2008 ide also suggest looking at the afm. also wouldnt hurt to take a look at ur coilpacks/plugs. a failing coil, would make the car idle poorly (sound like a wrx, as its runing on 5 cylinders) and would make it run like a dog with 3 legs.

abu Posted August 4, 2008 Share Posted August 4, 2008 intercooler piping? If an intercooler pipe is blown it will run really rich, miss fire and won't be drivable Link to comment https://www.sau.com.au/forums/topic/230618-ruff-idle-car-blowing-smoke-what-could-be-the-problem/#findComment-4055059 Share on other sites More sharing options...
Shadz Posted August 4, 2008 Share Posted August 4, 2008 +1 for the coilpacks! My car was/is doing almost exactly the same thing. Blowing out a bit of black smoke and smelling like fuel when you start it up? My car is at the mechanics now and waiting for a new set of coilpacks to come in. It was fouling the plugs and make the car sound and go like a tractor. Only like 30kmh, misfiring badly, lucky it happened on my street coming home.

Cooper Posted August 4, 2008 Author Share Posted August 4, 2008 Just pulled my coil packs off and they look fine. Im glad considering they are splitfires and have only done approx 5000km, i will be pulling out the spark plugs and cleaning the afm's tomorrow night, and also trying to follow the intercooler piping to see if theres a leak. I think ill need to pull off the front bar to see all the piping though.

Cooper Posted August 5, 2008 Author Share Posted August 5, 2008 Just took out the spark plugs, they are very dirty, very black. Any easy ways to clean them? Can i just wipe them off with some metho?

Cooper Posted August 5, 2008 Author Share Posted August 5, 2008 Well they are only as old as the coils (about 5000km if that) and are $20 a pop so id rather clean them rather than replace them.

rawd Posted August 5, 2008 Share Posted August 5, 2008 i had the same problem with running on 5 and rough idles after replacing my spark plugs. turns out my coilpack harness/plug thing was all cracked up inside and wasn't lining up with the coilpack properly. worth checking.

Cooper Posted August 7, 2008 Author Share Posted August 7, 2008 I just cleaned all my spark plugs thoughly and checked over the coil packs and the harness, the problem is still there. I also had a quick look over the cooler piping and couldnt see any pipes off but i need to take of the plastic guarding to see all of it properly, thats for tomorrow night. Im so worried its something engine related (because of the oil smoke) and will be major work to fix, i just spend a shit load on replacing stuffed turbos with my car off the road for 6 months so i can not afford to do any engine work.

700HP-GTR33 Posted August 7, 2008 Share Posted August 7, 2008 Well they are only as old as the coils (about 5000km if that) and are $20 a pop so id rather clean them rather than replace them. Have you got an After market ECU. Sound like the fuel is not burning properly...or you used poor fuel from a garage. My sister in law filled up twice at the same servo and both times she could not get the car started the next morning. It will blow heaps of smoke and splutter and kick like a mule till it has cleared the lines.I know cause I started it by pumping the gas to get the engine to kick. I would suggest you report it to your last fuel station. Get a new fuel filter and maybe if your like me, dump your fuel. I suggest all you out there to either use Shell or Mobil for your fuel. All the rest may have quality problems and may or may not address then. Good luck with the fix Link to comment https://www.sau.com.au/forums/topic/230618-ruff-idle-car-blowing-smoke-what-could-be-the-problem/#findComment-4064196 Share on other sites More sharing options...
Cooper Posted August 7, 2008 Author Share Posted August 7, 2008 (edited) Interesting. But i first notice the problem just before i got to a servo to fill up from empty and it has gotten worse with the new fuel. Both fill ups were from Mobil.

DLOOOK Posted August 8, 2008 Share Posted August 8, 2008 So is it making any boost @ all?? If not hopefully its just a boost leak in your plumbing or BOV.
