HELP!!! LT1 stalling?
First off, Great site!
2nd off... Here's the sticky.
I just recently purchased a 94 Formula Firebird, LT1 T56.... great car, i love it with a passion.... it has a JASPER remanufactured crate engine Less than 5000 miles on it, cost over 8 grand to build. MSD optispark, Flowmaster headers, full flowmaster kit exhaust, lightened flywheel, lots of power, lots of noise, perfect. well kind of.... on 3 occasions now, its just died... like i turned off the ignition to it. the engine is about 3 years old since build, (former owner) and i dont' quite know what all parts are in this beast... when it stalls, it literally just turns off, no warning, but starts right back up, either via starter or popping the clutch. the Service Engine Soon light is on, and its throwing 4 codes. a LOW TPS Voltage code, a AIR system code, and 2 AC system codes (its disconnected). My guess is one of two problems... either a faulty MSD Optispark... note it was brand new during install... less than 5k miles... or a fuel pump relay... or some other ignition controled relay.... mabey getting too hot or failing somehow... if anyone has had this issue or has any ideas please please please shoot it to me... two of the times its stalled its done it while driving/cruizing. once it was during idle.
Thanks!!!! i have two other problem posts so please check them as well.
