Hey guys, I have a 95 gt I just built about a month ago. It’s got cobra intake manifold, gt40p heads, a Ford B cam, new pushrods, rockers, and lifters, BBK 70mm throttle body, cold air intake with stock MAF and stock injectors (3 replacements) and a bama tuner. Before I built it it was definitely misfiring because I could hear the flappiness from the exhaust and a slight backfire. The misfire was still there after the engine was built and about a week ago it started breaking up over 4000 rpm. Just today it started up, idled for a few minutes, and shut off. If I gave it gas it would run fine but once I let of it would stall. This was happening on stock tune and once I set my idle screw at about 1k rpm I was able to get it running on my eco tune, it still wouldn’t run on stock tune or any other tune. I would say bad tfi module with the misfire and breakup but it would run if I gave it gas but die if I let off almost like it was running really rich. I’m not sure if this has anything to do with my problem but for about a year or so I was getting a check engine light that would stay on for a minute and turn off, when we tried to pull a code we just kept getting error messages on the code reader. Could I need a new ECU? Thanks.
