I've been searching and reading and combining this with what I already know. I'm not sure if the ecu has been re-tuned, but it has an aftermarket header w/o fresh air tube, no cat (so I was told) and the aiv, egr, bpt and vacuum lines have been removed. The motor ran rough and vibrated the car when I bought it Sunday. Tuesday I checked the oil and it smelled a bit like gas. Yesterday after it sat for a couple of hours I started it up and it had a lumpy/lopey idle. Today I pulled the valve cover and as soon as I broke the seal the gas smell was strong. Plugs look normal, not black or burned. I know some fuel that doesn't burn gets into the oil. I also know that bad rings and faulty fpr/injectors can cause this. Can the lack of stock components be the culprit e.g. aiv, egr, bpt, cat, and vacuum lines? If so I'll pull all of it off the motor I have in my garage. Today I will check compression and fuel pressure. Thanks in advance for all the helpl

check to see if one of your injectors is leaking, the idle air control valve needs to be hooked up so definately check the vacuum system. there are diagrams on here to remove egr i believe i put one up years ago. next check the seal around the the injectors. (spray carb cleaner around the injectors youll hear the idle change if they are leaking) check the compression, check the timing, look under your car make sure you do not have a cat, if you do check to see if its clogged. reground your MAF (there is a write up on that as well)

thats all i can think of right now.

awesome, thanks! the maf has been reground, not sure if it was done properly though, I need to check resistance.
