TFI module help
 

It seems like I have a screwy problem with either my eec or tfi module. I can start the car cold and it will idle just fine for about 5 minutes until it warms up. then it sputters and backfires a dies. As soon as it dies, there's chirping going on inside the distributor. If i take the distributor cap off, then the spark jumps from the coil wire to the primary wire terminals on the coil. It's like on a points system the points are opening and closing without it running. Do i have a tfi module problem or something else. THe car is kind of a complicated mess. I have converted from an aod to a tremec tko trans and am still using the aod computer. It's had some idling problems ever since the conversion. I would probably help myself out by getting a manual computer from somewhere. But i am not sure if i got an eec tuner if that would help matters. Any help is greatly appreciated. It's getting very frustrating.

It also has an msd 6al, with a blaster 2 coil and a vortech/msd boost timing retard on it. I had a weird problem several months ago, where i was cruising about 75mph, and it wouldn't quite hold it's own, so i'd try and downshift. but when i'd let off the accelerator and disengage the clutch it would die. Shifted down to 4th and let out the clutch and it would come to life again, but still wouldn't hold it's own. so i barely got it into a guys drive and it died. messed around for a while and couldn't get it to start unless i would push the accelerator all the way to the floor. finally it started and ran like normal again. and didn't have any problems with it for 4 or 5 months until now again.

Run the codes and see what the EEC tells you is wrong. You may have sensor problems.
