Hello all! I have a 1988 mustang 5.0 gt conv. And I'm having a issue. The car starts up fine when cold and will have a steady idle. It will drive good as well. But when I shut the car off after running it and start it up it will stall, I can keep it running by holding throttle, if I hold throttle for a min I can get the car to idle on its own but the rpm jumps up and down.....Tps is at .96v and just replaced iac and have 10.1 ohms. So those are good. Any suggestions? And I smoked it to see if I have any vacuum leaks, didn't find any and put computer to it and have no codes.
check your coil its a 25 $ part i had same problem recently cold would start and run when it was warm it would spit and stutter then die!
