A friend recently had the timing belt tensioner break on their 2.4L dodge caravan, it has 140,000 miles. I replaced the tensioner, timing belt, water pump, and had to change the harmoinc balancer due to a chip in it. When the vehicle gets up to temp the idle becomes slightly erratic, and it will die when coming up to a stop. The timing marks are all correct. I checked the MAP sensor and it's good, as well as the PCM. I did a vaccum check and it held at 16hg. I can't hear any tick or other noise that indicates the valves were damaged when the tensioner broke. The only thing I have not checked is the crankshaft position sensor, but I don't have an oscilloscope. It sounds and runs great up until it reaches operating temp, then it gets just a slight sputter and dies when coming to a stop. Any help would be greatly appreciated.

 

Welcome to DF
Do you know if an impact gun was used on the camshaft spockets?

 

Thanks for the welcome. No impact was used, I just used a box end wrench on the cam sprockets.

 

Check the wires going to the crank sensor and the cam sensor wires too.
