I have an 86GT. My problem is I bought the car with modifications already complete. Cold air kit, Mass Air Flow sensor, MSD6 ignition, BBK65mm throttle body, Underdrive pulleys, BBK shorty headers, and Flow Masters. On initial start up the loads up on fuel and surges badly. After about 5 minutes the motor cleans out the excess fuel and runs very well. Any ideas on my start up problem?

I'D MAKE SURE the mass air conversion was done right..I believe there is something about a vss connection that can affect such things if left not wired up..but someone more knowledgable on that may be able to help you..just something I remmeber about the conversion;)
