Well since i have had the car its been backfiring... i had a new fuel pump put in, felt great at first, then it started backfiring and there were dead spots, id hit it and nothing happened

So i bought a Adj fuel pressure regulator from Kirban...

had it in felt a little better but im having the same problems

Before the new fuel pump i was running at 20 or so PSI fuel pressure

could running that lean have damaged my spark plugs or wires?

somthing just isn't right.

Full Exhaust and the fuel pump and reg are my only mods, and a new rack and pinion steering.

 

i suppose when you had the tank down, you didnt bother to check if the fuel pump baffle was still in place inside the tank.

check the MAF sensor wires too, if they aren't as white as a piece of paper, clean them.

 

ey try the fuel filter it just worked for me. that is if you have a problem with the intake.

 

well, i purchased a BRAND NEW tank, cuase the baffle in my old tank was broken. i really hope the baffle has not broken again. my cousin had noticed tonight on turns it does it alot, but also while im cruising, ill feel the car dieing then i punch the gas a little and itll POP and go normal again.

 

put a half tank of gas in her, then hit corners, this will tell you.
