Im not sure what the problem is.

I went out a little while ago and was just screwing around with it. At this point im just bumfuzzeled...lol. When I first crank the car,when its cold, the car wont rev past about 2 or 3 grand. It just kinda bounces from idle to whatever rpm, no matter if floor the gas peddle. Then it will move up to 5 or 6 grand and do the same thing, like its got a rev limiter. Then when I can finally get it to rev to redline it pours out oil smelling smoke. I can drive it once I get the car to rev to at least 3 grand...just kinda hard to accelerate. Another completely baffling thing is, I can rev the car a few times to the upper RPMs and then itll pull like crazy for a few seconds to a few minutes. Then all of a sudden, the car pitches forward hard, like I hit an invisible wall. Its like I switched my fuel pump off,then back on. Then I shift gears and the same thing, hit a certain RPM and the wall is there. And it varies from about 4 up to 6 or 7 thousand RPM. But, once this happens and I let off the car wont pull hard again, unless I pull over and turn the car off and crank it again,then same thing again. Any ideas? If this was a wastegate or turbo issue, it wouldnt go away and come back again. Or am I wrong? Anyone have any ideas???

I'm no guru, but have you checked you replaced you're fuel filter or checked you're fuel pump's connections, could be a bad ground or something. Also the injector's may need to be cleaned. Was the car sitting for a while or did this just happen one day?

 

check the tps and all the usual other things.

 

my car does the same thing, relatively new fuel filter too, a few months old. Im na though. no oily smelling smoke, and i dont have to switch the car off to make it go away, just randomly comes and goes.



Maybe i will change the filter again, and back wash it to see if there is much debris, this happened right after i changed my fuel lines. and cleaned the ecu ground.
