First timer!! Need a little help
i got a 89 mustang gt. i have a complete rebuilt motor, punched out to a 306, upper and lower GT-40, rebuilt heads with stainless steel valves and dual springs, BBK shorty headers, BBK 190lph fuel pump, BBK fuel pressure regulator, and flowmaster exhaust. i just got it running. for the first week it was fine,but lately its been running HORRIBLE. I could be driving, then its like the motor just shuts off for a second to two and the RPM's drops as well. Lately its been getting worse and worse. i took to my work to hook the NGS to it and it wouldnt comunicate. one of the guys i work w/ says its my PCM going out. Do you think thats what has been causing my car to act so crazy. Also what could i put on next that could really help me out? Anything will help.
