ok so i just got my tII swap into my gtu finished and now i'm doing last minute tuning and body work, but at the same time, i have a weird problem i can't figure out, the car when it is decellerating, it makes a weird bogging noise and revs down very slowly, even when i and just sitting still revving it up and letting it idle down, it idles down slowly and makes a weird bogging type noise... anyone out there with some opinions let me know

 

If i recall correctly when the revs go down very slow its a lean problem. Anyone else have input on this for him?

 

Backfiring is a sign of rich mixture, adjust your TPS maybe.

 

I know my tps needs adjustment and fuel mixture is messed up, how do i adjust it? i know how to adjust the idle but the other two screws make things complicated

 

anyone have the link to the FSM i need to figure out this tps adjusting
