OK this weekend i took my car to a guy that knows mustang . He has a 92 gt with a vortect superchager blah blah blah but he did all the wrok him self so i knew he could help me get my car to stop running so rich He nottiched that i had some vacuum lines were really old and that they some have broken and then he said that something was umpluged to my smog pump
we both didnt know it was but heres the part # i got from it
E4TF-9C915AA
So does broken vacuum lines and a f uped smog pump sound like a good reason for my car to run rich

Do you have an aftermarket cam? Or any mods? A cam made mine run rich.

Im honestly not sure about the Vacuum lines but i know for me atleast an aftermarket cam made mine run rich.

Also how long have you owned the car? maybe the pervious owner had it chipped, did you check the computer at all?

What mods do you have on the car now?

[86gt t-top]

alll i did to that car a was a cat back exhaust and a cold air intake

i have onwed the car for 6 months and it has alway run rich but the guy before me said that guy was making it into a dragster and but then got another project so i really dont know excatly what was done to it

Well it could be possible you have a Cam upgrade.

You will know for sure if your cars cammed. Can't mistake it for anything else, minus a huge MIS.

ok one guy that drove my car said it had more pep compared to his stock 87 gt and so mabye it does have a cam upgrade
so is there any way to try to get the smoke and smell down with out getting a new camshaft

[flattusmaximus78]

Some bolt on foxes run low 13s and others high 15s. Do you have an idle video? I have an fcam and when my car starts up, it cams hard as shit... its more then ovbious.

[flattusmaximus78]

You have smoke too? What color and how long does it stay around, or is it just start up, or everytime you get on it, or at all times?

[chewey]

vacume lines worn or broken on most vehicles can cause them run rich i have no smog equipment on my car perioud lol and it runs great, and as far as the cam goes you either have one and its loapin may be even rockin the car at lights dependin on the cam or like what was said ya have a huge miss, but most engins missing that bad tend to wanna spit and or try to cut out at hard accelerations, just been my experience anyways

well when i do sit at a stop the car does rock alittle and the motor does cut off sometimes after i do a big burn out but when i accelerate hard with some grip with my tires the car run great

WTF y cant my car just run right

[superbean]

is it converted to maf? a vac leak on a maf car would cause it to be lean.

It sounds to me like you have a foul o2 or stuck injector.

Try tapping on the injectors LIGHTLY with small screwdriver, one might be stuck.

[86gt t-top]

how would i tell if my injectors are stuck

[saldoggs]

do you know what size your injectors are if not what color are they that will help you figure out the size also what is the fuel pressure at some guys used to remove vacuum from the pressure regulator to make more pressure to get more out of the car that's OK if you have a stock pump but if you have a 190 or 255 pump in the truck you will have way to much pressure
