ok again, i have 92 GT with minor bolt ons. intake, 65mm T/B, msd 6A(which is not connected), msd coil, headers, full exhaust, pulleys, CAI, and 73mm MAF

recently my cars ecu went bad and i replaced it with a A9P and since then iv had this horrible surge (sometimes buck) while cruising, slowly accelling and at idle.
today i replaced the MAF, TPS and set it to .98, IAC, ACT, CTS, set timing to 10 degrees, set FPR to 40psi, did a base idle reset and sprayed carb cleaner everywhere with no changes. after that it now bucks and will slowly accelling and cruising
when i unplug the maf it will rev up and run smooth for a minute or two and then start running bad again.

if anyone can help, i could really use it. this car has not driven right in almost a year.
