whats wrong!!!!!

[97vertstang]

im banging my head once again. my car is idling bad, i can smell the fuel , and its backfiring through the exhaust. i put a aeromotive FPR , got the fuel pressure to 44psi vacuum on and its still doing the same thing. if i get on the car good , it feels good, but between idle and 3500rpms it feels flat and the idle is shitty. im done for today, but what could be wrong??? 02 sensor's??? the distributor module???msd box???? give me some ideas guys!!!!!!!! thanks

the fuel pressure gauge i had was wrong. i got a new one and adjusted it to 35psi. the car idles like shit for about a minute and than it smooths out. for that minute u can smell the gas. if i drive it for 30 mins i can get home and the car drives beautiful now, but once i turn off the car and turn it on it will idle like shit. for the 1st minute it will idle like shit no matter what i do. i cleaned the iac,cleaned the maf, checked the tps, disconnected the msd box and still the same problem.what can it be???the only thing i can think off is the 02 sensors?????

clean the MAF?

it's never going to be the maf.

Check your IAC.

yeah you may just need a new one, even though you did clean it. idk really what your problem is though. sorry =/
