91 gt/cobra

i have a 91 gt/cobra with a 302 at .30 over with gt 40 heads that are ported and polished with a crane b303 cam and short tube bbk headers... and my bubby was tellin me that thats its runnin to fat and he dont know how it fix it and neither do i... but the guy i got the car from said it was out of time and i fixed that but when i drive it and i come to a stop it stalls on me and i really need to figure out whats is up with it. . . and my buddys dad said since it has gt 40 heads that the mass air sensor might be bad and that could be why but he aint sure... so any help would be appreciated... thanks...!!

what the hell do you mean by "fat?" running rich? running lean? running at too low of idle? try driving and the parking in your driveway, hurry and pop the hood before it shuts off and smack the Idle air control motor with a wrench and see if the idle cooperates. if it does, replace your IAC...need more info

start by calling your car a GT, so you dont get flamed.

Have you ran a KOEO and KOER self test yet?

Yup just a GT. Your car must have a Canadian title originally.

Also if you have a b303 cam its not a crane cam.

run codes and how or what did you use to verify a rich condition...your nose?? = lol

Running to fat...reckon it means that big girls are attracted to his Mustang.

From what I understand, when they start running too "fat", they're as good as dead. The only option you really have now is to sell it, and buy a 3rd gen. Camaro for you and "bubby" to cruise around in.
