Re: 05 caravan stumble hesition
yes my crank and cam difference is at max -1.0 and i also scoped the crank and cam and the wave forms dont do anything funky while it is doing it down the road. so the sync is good and my wave forms also look good. my question is i here the flex plate cracks on these but where?? i pulled the inspection cover and i didnt see any cracks or anything. i am getting puzzled over this thing.. fuel pressure while its doing it is 58psi. the only way i can discribe whats going on under light throtle something feels like its shutting down or like its dogish. but if u step right on it like caughs and goes
