Hey guys, Having an issue, i havnt really dug into it too deeply, but wanted to see what yall think. I have a 1993 gt with a tfs headed high comp 347. Ran great no issues really. Took it to SCCA ran the course no issues. everything has been running pretty decently for a year or two now. I parked it after the last race session. went to go fire it up to move it around in the mess i call my driveway and now it barely runs. It fouls the plugs like crazy and i cranked it over with one of the plugs pulled and it shot gas out like it was a super soaker. Its a stock A9l with a moates QH. I tried uploading an older tune that worked decently before, still same issue.
My question would be, what would cause the ecu to hold the injectors open? Bad connection? A filleted wire touching ground? I dont even know where to start. I keep leaning towards a toast ECU. but it tries to run. Any suggestions would be great. The injectors have been cleaned, flow tested etc. Fuel system is relatively new. Its holding 37 psi of fuel pressure (its what the tune is based off of) O2 sensors dont have too much mileage on them.
Thanks!
