bleh, vintage air is too much work for too little gain lol. Electronic would be nice but I'm done modifying for now, I want to drive this damn thing!!
Ok, actual issue and question... Not sure if I should start another thread or ask here.
So, today was a tuning day. I got the IAC, TPS, Fuel pressure, blm's etc etc all within specs. I also tuned the transmission and set that up correctly. It has a heavy duty actuator and boost has been at about 17-18 pounds with the alky set at its base number, 6 I believe. Car starts, idles, and drives amazing. Has an amazing amount of power for 18 pounds of boost and I haven't seen any knock retard yet even with no alky at all but I had it on for the test drive to be safe.
So after getting it dialed in we went on a 20-30 mile test drive. Freeway, side streets, WOT, idling etc... Just to make sure all the bugs are out of the system. Then all of a sudden I get a weird shudder and the car starts sputtering and backfiring and dies. Car will start easily but immediately dies with a nice backfire. After it cools all the way off it starts and runs fine for a minute then the problems start back over as soon as it heats up.
Fuel pressure is fine, no malfunction codes, alky is working fine and tried turning it off, all the scanmaster readings are fine with the key off (car wont run long enough to check the numbers while its running). Balancer bolt is tight, camshaft sensor is tight, its not vapor locked, it has gas etc. Thought maybe the coil pack so we changed it but thats not it. I have a camshaft sensor and coil module on the way since those three seem to be the most likely culprits but were guessing.
Am I missing something, any ideas!??!
