well ive gotten the boost cut thing taken care of, now i have another problem. This is what is going on now. When i drive my car, it runs lean, spits and sputters and doesnt want to go when im not on boost. when I get into boost , the car runs out great. This is the case about 85% of the time. the rest of the time the car runs fairly well, good a/f ratio, but will sometimes get rich if i barely let off the gas. Then after i modulate the gas again, it starts running like crap again. It s the same wiht the idle except that it is more like a 50:50 ratio of good idle and crap idle. could anyone give me some suggestions on what might be wrong.
thanks

 

Just a guess, because I didn't read your other threads, but have you tried injector cleaner? And are you getting oil in your intake?

Checked your TPS?

 

what do you mean about getting oil in my intake? There does seem to be a certain amount of oil in the intercooler and in the upper intake manifold every time i take them off. Is this what you mean, if so is it a problem, if so , what is the fix, thanks.

 

also, yes i just bought a new tps the other day and i cant get the car to run if i set It to the 1 volt it needs, it has to be at about 2.85 to run.

 

Sorry, I spent a lot of time trying to find your post again.

Oil in the intake may mean your compressor oil seal has gone bad. If there's just like a light coat of oil and some crusty gunk, it may be just the PCV system (although there's no valve like in a piston engine), or backflow from the intake charge shuttling back and forth through the intake. If there's a heavy coat of oil, like dripping/puddling in the intercooler or pipes, you may have a problem.

Too much oil in the intake can cause ignition problems at idle. You'd be able to tell this by looking at the plugs. If they're cruddy and covered with a black sludge, you've probably got oil seal issues. If not, then it's something else.

I don't have a TII, so I'm just making a guess here, based on personal experiences with NA 13B's, as well as boingers (my 86 944t had a blown oil seal which coated the intake with oil... yay...).
