2003 Dodge Ram 1500 5. 7 hemi, electronic throttle will shot off going down the highway which makes it idle bad and loose power , have to stop on the side of the highway and shout off the truck and re-start hwich will reset the throttle. The problem will happen at speeds from 30 miles per hour to 75 miles per hour it will happen using the pedal our on the auto control and with or with out the ac on. Safety problem have to stop on the side of interstate 95 or the 495 belt way and restart the truck very unsafe for me and for the other drivers around me. The problem will happen every 150 to 250 miles, I have taken the truck back to Dodge many times and spent a lot of time and money trying to get the problem fixed but Dodge is unable to find or fix the problem. One time Dodge did find that the truck had bad springs in the engine that they replace( bad from the plant ) and they hoped that would fix the problem but it did not. This problem started after I got the truck from the dealer used ,it had 40,000 miles and at 46,000 it started and has not stopped the truck now has 94,000 miles and I have to stop every day on the road to reset the throttle. First date of problem 05-01-07.
We purchased a 2003 Ram 1500 3. 7, in 11/07, the truck has not been running right, we took it in and 2 plugs melted, into the coil, the dealer replaced the heads on that side. We picked up the truck. And the serpentine belt fell off and froze the water pump, blowing another head gasket. This isn't the first time the pump had been replaced.
I own a 2003 Dodge Ram 1500 2x4. Clutch was replaced at 36000 miles, and motor was rebuild at 46000 miles, both times under warranty. Each time I' had the oil changed there appeared to be a white substance building up on the oil cap as if it was condensation. I now have 88000 miles and have a "ticking. Like a valve sticking, and continues to have this white substance. When it rains or I go through a puddle of water the belt starts to slip and all power is lost.
