The van has no power under load, surges and stumbles at times. You can drive it up to 45-50 mph if you very gently accelerate, above that it starts to fall flat or if you jump on the accelerator it will stumble and hesitate. The vacuum reading is low 11.5-12in with a fluctuating gauge but it will smoothe out some around the midpoint of the rpm range, the compression is 160 psi plus on all 4 cyl. It has a new cam and crankshft sensor the timing marks all line up it acts like the convertor is plugged but its not, the pcm has the software update sticker on it, fuel pump psi is 60 plus at idle. I am leaning towards the crankshft tone wheel is that possible and replaceable.
