    I had this same problem and found that The EGR vavlve was not returning to the closed position at idle. Ran fine going down the road but would not idle when I slowed or stopped. Removed the EGR valve found it was full of carbon and occasionally a small chunk would break loose and stick under the valve. Cleaned the EGR valve reinstalled it and it cured the problem.

    Not the easiest to remove - but it's easy to clean... better than buying a new EGR valve which is quite costly.

    Remove air cleaner - use a long 3/8 extention with swivel only 2 bolts just a bit awkward to get at. Unplug electric and it come right out.

Low idle sensor is probably bad.

Run the engine for one or two minutes, and then stop it. Depress the brake pedal several times at normal foot pressure. If the pedal goes down further at the first time, but gradually rises after the second or third time, the brake booster is functioning properly.

Do serpentine belts stretch?


serpentine belts do not stretch as you describe because the tensioner keeps them tight so they just break. It is probably hard and cracking and need s a new one so try that first . The ac has nothing to do with the belt as it will be a low gas problem from leaks and the heat is a coolant problem or a control problem from inside the car.. The grinding sound may be a pulley bearing or some other bearing failing. Why don't you take it to a repair shop to find all the faults so that you can work out how much it is going to cost.

My 98 dodge ram vibrates bad at 40 mph plus at a steady low rpm. if i step on the gas it kinda stops and if i let go of the gas is stops completely it also started misfiring when it started this


Torque convertor shutter? Maintain the speed that it does this, and with your left foot, apply a small amount of pressure to the brake pedal. Not enough to slow vehicle, but enough to disengage the lock up convertor. If it goes away, try servicing the fluid with new 7176. if that doesnt do it, replace the convertor.
