Im pretty sure im runnin to much fuel because im seeing some black smoke at high rpms like around 4000-5500. My car also bogs occasionally at lower rpms and at full throttle. Is to much fuel my problem? How can I fix this? Anyway I could be wrong its just my guess, THX.

to adjust fuel pressure you need an adjustable pressure regulator... but its not likely your having a fuel pressure problem (rich wise) with just your mods. Maybe tps? Not sure, you gettin any codes?

Yea a buddy of mine has a 95 and he was sorta have the same problem, with the bogging and what not, but he got an adjustable fuel pressure regulator and he said it helped alot i dunno i just wanted to see what u guys thought, and im a newb so i dont know what tps is or what "getting any codes" is

yea with your mods you shouldnt be rich. when is the last tiem you had a tune up? try that along with adjusting your TPS. if youre wondering about the TPS do a search. its been discused many times

getting codes means, when u run a computer scan on ur car...... the codes are the problems that it finds. u look up the code # and that tells you the problem

yea i figured it out right after i posted lol. well n e way thanks ill maybe do a tune up and check some stuff out. thx

bobby

cool, let us know how it goes

is it possible to have codes stored, even tho the light never came on?

Yes.

Also, I am having the same issue right now. I get some black smoke at the higher RPms which bugs the **** out of me. I just haven't had the time to adjust the fuel pressure. I need to pick up a voltmeter and check my TPS though. I think that might be the cause of some of it. It semed to start after I reinstalled everything after the polishing party. Oh well, bet rich than lean.[&:]

to rich will cause hurt in performance by a great amount. but yes rich is safer
