I have a 1999 Dodge Caravan with a 3.0 L. The engine is missing under load, and I get a report of misfire in cylinder 1 when I read the codes. Garage has tested everything: spark plugs, injector sugnals, fuel pressure. I did a tune up (wires, rotor, dist. cap) no help. Had the fuel system cleaned too, no help. Swapped plugs around, fault stays on cylinder 1. Just recently I have started to get a MAF sensor fault (reads high impedance) and a multiple misfire code too.
Garage doens't have a clue, other than possibly a bad injector for the missing. Anyone have some other things I could test or read through ODB II? I have a scanner.
Any help appreciated.
