i have a auto 95 jetta and when u hit the gas somtimes it just doesnt go anywhere. idles really low 500-600 rpm. when driving it just kinda chugs along and u have to pump the gas a few times to the floor until it gets past around 1500 rpms, once past that stage it drives perfect. ive been told a few things it might be so far. IACV, distributor, camshaft position sensor, major tune up, fuel pump and fuel filter just got the car at a auction so i dont know the history. any advice would be greatly appreciated thanks.
