Engine Performance problem
1999 Dodge Ram V8 Two Wheel Drive Automatic 189k miles
1999 dodge ram 1500 5.9 automatic, I can be driving along and suddenly the engine starts flooding out and backfiring through the intake. Have to pump the accelerator and downshift manually to keep it going. This happens at any speed and more prevalent when motor is under load in higher gears or cruise. But also happens during idling.
Only happens after warm up to operating temperature, no codes are ever thrown into PCM, fuel injectors have been swapped out fuel pressure remains at manufacturers recomended pressures even during flooding. Entire exhaust and 02 sensors, compression test has been ran, PCM swapped out with a known good one, all throttle sensors changed.
I have had it into chrysler techs 4 times during the last 2 months and no one seems to be able to find the problem
have the same problem?
