This is a 1999 Dodge 5.2 V8 in a Ram Van 1500 and it has always preferred to run on 5, 6 or 7 cylinders, never 8.
<br/> All the Chrysler TSBs for misfire were performed, the engine has new heads, burns no oil and has 150k and good compression all around..
<br/> Injectors removed, cleaned and tested, all new Autolite Platinum plugs, all new wires, new Bosch Oxygen sensors.
<br/> First success to get to 6 cylinders fireing was a new Crankshaft Position Sensor.
<br/> Next was to clean and re furbish the PCM module connector contacts and this got things to a reliable 7 cylinders.
<br/> I am out of ideas. Help!
