Alright heres the situation my car was 25degrees advanced i set it bck to 15degrees... but there something wrong with my IACV either bad ground or its broken all I know is that its stuck and i have to set it manually so it works... now wen im shifting it pulls around 3200 like if it wants to go then all of a sudden im pressing on the gas but the car doesnt pick up speed and that happens in every gear before i did the timing it didnt have that problem
