Ok, T3/T4 turbo, 255 fuel pump, SR injectors... blah blah blah. AFC-2. Ok, driving..... the car is fine... when I come down to an idle it bogs and if I don't give it gas, it shuts off. AFC is reading fine... A/F is fine, Batt. is reading 13.9V. Knock is around 10-30, when it bogs it goes up to 80. Also, when it bogs... I smell gas, but it's like a "bad" gas smell. Like the gas is old. I'm running 87 octane.... I'm beginning to think I should use 93. Any suggestions??? I need come help... what to check... so on and so fourth. I checked all the vaccum hoses, everything is plugged in. Could it be bad gas doing this????? IT didn't start until I filled up last night. HELP!
