1998 dodge grand caravan 3.8 L cleaned throttle body, replaced plugs and wires, replaced fuel pump filter and sender, intake manifold is very dirty with carbon changed oil, removed and cleaned map sensor, throttle position sensor, getting code saying that map sensor and tbp need replacement
It sounds like an issue with the vacuum advance. The timing is not catching up to the acceleration.
Have you checked your ingition coil it is probably cracked and arking. Use a spark plugs and tester to confirm. The spark should be bright. If it is dim from the wire to the ingition coil. You have a bad coil.
Testimonial: "wasnt cracked, replaced it anyways. still doing it although slight improvement in how its running. What about poor ground wire for electrical?"
Mine is bad. IS NOT WORKING.

fuel pump is working but when accelerating it doesnt pump enough fuel up to the engine then it will fall on its face if it is a electric pump you may have to drop the tank if it is inside and replace it if it is on the engine replace it thats what is exactly wrong with it

Van misfires, code says coil three . change out with new a cam sensor , injector, wires , plugs and of coarse coil. What is left and why would the pcm just have a problem with # 3.
ps i checked the compression and all six cylinders have 165. lbs.

Sounds like a vacuum leak.

How does the exhaust look. White rich of a fuel smell??? Or look normal. Does you exhaust raddle noticably. That can indicate a fuel injector stuck open.
