Ok, still running a ka24e. The car is functioning fine. I put everything back together after a warped head (milled to specs, with new gaskets all the way around.) I get the car running, and it runs great for about 2 weeks. I come home from work, park the car, shut it off. I go out the next evening for a quick ride, and I start it up. It's idling like crap, I can smell raw fuel, and I have a ton of smoke coming out of the tailpipe. Its white, and it smells like unburnt fuel. I already knew my fuel pump was about to call it quits. So I replace the fuel pump today, fuel filter, strainer. I also tested my TPS, and the voltage at idle, and at WOT were way off, so I replaced it as well, hoping that it would at least rememdy the problem. Well it allowed my car to start now, but it is still idling poorly, and I still have white smoke coming out of my tailpipe. I did a leakdown test, to check and see if there could be some chance of more head problems, but it checked out fine. I pulled my MAF today, and noticed that the heated wires are coated in carbon. Could a faulty MAF sensor be doing this? I also just had the injector wiring harness redone (nissans problematic corrosion problem with the terminal ends.) Any help would be great. I'm lost, and FSM is in Cali. I've never had a problem like this before. Thanks in advanced. Coil? Ign. Module?
