1995 Supercharged Gt Stalls When Warm?

[MustangFan82]

I bought a 1995 Supercharged Mustang GT, It has some engine work with a Kenne Belle Blowzilla supercharger. It starts up and runs great for about 15 minutes then once I let it sit and idle it will hiccup a few times and stall out. If I try to restart it it cranks and cranks. If I get it to start it runs so rough and wants to smoke a little. If I let the car cool for a few minutes it will fire right back up. I changed plugs, plug wires, Cap and Rotor and the Coil, and still no change. I gapped the plugs to the required figment per the superchargers specs. Any ideas?? I'm going to clean the MAF sensor, And change the fuel filter in hopes that will fix it. Maybe the ignition control module? Throttle positioning sensor? If anyone has a thought or has encountered this please let me know. Im not throwing and codes so I cant scope it, Thanks!

Our cars very commonly have problems with the pickup in the distributor (PIP), and when the ignition module (TFI) fails it also fails in a similar fashion. Basically when it gets hot, it runs rough and dies, and won't restart until cool. Then it acts like nothing happened until it warms up again.

These type of symptoms can also happen with a failing fuel pump, so checking your fuel pressure when it dies is a good way to troubleshoot. But I'd guess the PIP or TFI. When mine failed, I just replaced both. The PIP is a bit of a challenge to replace by itself (pressing the gear off and then back on without wrecking it), so many just replace the whole distributor.

Are you saying just because you don't have a CEL you don't have a trouble code? Lots of codes are logged without a CEL showing. If you have a code reader use it. There well may be a code that will point you in the correct direction. Do you know what tuner is managing the ECU function or is the ECU an aftermarket stand-alone?

Thanks, I was thinking along those lines aswell. Im going to get the car put on a scope to see If I can pinpoint the exact problem.

Yes, My CEL isnt coming on, So I was figuring it couldnt be a failing sensor. But I know thats not always true. As far tuner Im not sure, Pauls High Performance in Michigan did alot of the work in 2002 and since the car has only had 4k miles put on it. So I figured the tune up would be the resolution. Ive got file folder full of receipts and work perfomed, Ill check and see if I can find something. Thanks for the help
