Well it depends on the year of your mustang. If its the 94' with the 302 then it could be your computer. I had the same problem. The computers they put on the first year of that body style didn't take well to modifications. If it is a 94' then I suggest replacing the computer. Either get a new one, or find one off a junked fox stang' with the 5.0 and it will connect right up.

so you have a cobra cam? man you just put a cam in your motor that is tamer then the stock one. cobra is more of a truck cam with its lift and duration. thats why they added the 1.7s to give it that extra umph.

but check your comp. alot of issues with modding a 94/95 ecu. alot do the swap to a fox ecu

to many folks all the see is the cobra name that it has to be faster/better

well reset your idle using a hex key..then readjust your TPS
