Hey everyone. I need some help with my car. I had a turbo 363 setup and I recently took it out to replace it with a 302 H/C/I. I had to replace the ECM harness cause the car would go crazy when I moved the harness around. The harness had been tapped into in a few places as well. I first took the turbo setup and left the 363 in it. The car ran great with no issues whatsoever. I pulled the engine and the car sat for about 6 months. I dropped in the 302 and it has never an correctly. The block is an old block that I had and ran good when I pulled it. Here's a quick run down of the parts it has: Edelbrock heads, which had a valve job prior to installing. TFS Stage 1 cam with 1.7 Rockers Edelbrock RPM 2 intake with an Accufab TB and Pro-M 80mm Mass Air calibrated for 24lb injectors 24lb injectors Fuelab pump with -10 feed and -8 return with BBRC rails (I know it's overkill but it's what I had with the turbo) T5Z Transmission The distributor is a Motorcraft unit that was bought new and might have a few thousand miles on it All sensors have been replaced Timing is set at 14* Fuel pressure is at 38 The issue I have is popping out of the intake while accelerating. It happens about 75% of the time. The car is down on power as well. I have swapped out mass airs and injectors with no luck. Also, if I disconnect the O2 sensors the car will really run bad. The sensors are new Motorcraft ones. When I had the car with the 363 it had no O2 sensors hooked up and it ran fine. I've been chasing my tail on this issue for about 6 months now and I'm about to call it quits. If anyone can suggest anything it will be greatly appreciated.
