OK, here is what I have replaced so far, distributer, cap and rotor, o2 sensor, map sensor, coolant sensor. Heres what it is STILL doing... the truck will run pretty good with the vacuum line OFF the map sensor and the vacuum line pluged, that way it runs good at idle but dogs a little when stepping on it. If I plug the vacuum line back into the map sensor it idles a little rough, runs worse until you step on it.
The only codes I am getting now (with the vacuum line off) is map sensor
(with the line on) o2 and knock sensor (13 and 43)
I am at a loss.
