TFI module replaced. It seemed much better but still a big hesitation if you hit the throttle quick so I knew it still wasn't right. I was laying under it while it ran looking to see where the exhaust leak was coming from. It ran about 10 minutes but I couldn't tell if the miss was a miss or just an exhaust leak. It died and wouldn't start again while I was under it. So the TFI module didn't do it although it seemed much better. I'm beginning to really dislike this thing. I'm wondering now if maybe the catalytic convertor is all plugged up. I hate just replacing parts till I find it but I'm at a loss. The racecar is so much easier to work on and fix. Non of this computer controlled emmision stuff that all has to work together or none of it works right. Ugh!
