Any advise would be greatly appreciated. I've got an 05 Ram 1500 Quad Cab with the 5.7 Hemi. It's ran great and I now have about 90K on it and it began missing very occassionally when I accelerate from a stop. I took it in to the dealer and they could not reproduce. Then one day starting at a stop light the truck missed and then clunked to idle speed and totally ignored the throttle with the ETC light lit on the dash. I restarted the truck and it was fine. I was pleased in that I thought we had a good symptom for the dealer to get to the bottom of the problem. The Odometer read P0522 Engine Oil Pressure Sensor 1 Circuit Low, P061C ETC Level 2 RPM Performance, P062C ETC Level 2 MPH Performance. The dealer said the Throttle body was dirty and basically blamed my K&N FIPK. They cleaned TB, replaced plugs and wires and performed fuel induction service. All stuff I thought good since I love the truck and want to keep it as long as I can. However, I did not get back on highway before it missed again. A week later it stalled accelerating and the Malfunction Indicator light came on and blinked. Another trip to the dealer and they simply reprogrammed the PCM. I did not make it down the road 5 miles and the ECT light came on when accelerating and the truck went to idle and ignored the throttle again. This time I got P0339 and the old P061C again. I've read the Hayes manual and it would sound like the ETC sensor might be bad since the engine is developing a nasty habit of ignoring the throttle. However, it also says the ETC sensor is an integral part of the Throttle Position Motor and the sensor is not a servicable item. Does it sound like the throttle position motor must be bad? Any suggestions greatly appreciated.
Thanks,
Mark
