Hello all!! I have an 04 gt w/novi 1000. My issue is when at idle it misses and surges when the idle drops below 1000rpm, and also bucking when I drive at a cruise state!!! Done new iac, maf, plugs, coils, and a vac leak test!!! When I'm under throttle and in boost it runs good and the fuel is around 12.8-13.2 wide open! Any help or advice would be greatly appreciated and thanks in advance!!!
