I know this is the wrong forum but this is where everyone is at so I figured I could get more help here than anywhere else. I've got a 93 GT and at about the middle of the summer I dropped a new GT-40 crate motor in from JEGS since the last motor crapped out on me. The motor is designed so that you can swap everything not included on it already like the intake, injectors, TB, etc...instead I put an Edelbrock Performer 5.0 intake on it and BBK 70 mm TB. I also have a 73mm MAF. The only thing that was left stock was injectors, fuel pump, and most of the spark componets(coil, cap, rotor, and distributor-they are brand new though). Now that the motor is broke in and I can get on it, somethings not right. :cuss: Starting at 3000 rpm's, it cuts out. I thought the A/F ratio was fcked up. So I replaced the fuel pump-255LPH. That didn't work. Next I put in 24# injectors. Didn't work. What the hell is the problem? Thanks for the help.
