I resently change out a water pump and had to take apart the complete top end of the engine except the cylinder heads. After putting back together the engine I have a problem with rough Idle and stalls at the stop signs. I recheck all the vacum hoses and check for vacum leaks and can't fine any. i also replaced all plug wires and spark plugs . Runs great going down the road but has a hesitation off Idle
Did you check the idle air control valve? See tips at the link below.

Check your EGR valve. It may be stuck open. I had a similar problem 2 years ago on my 97 avenger w/ 2.5L V6. Engine idled rough and would die when I stopped at a stop sign unless I feathered the gas pedal as I coasted to a stop. Replaced EGR valve, problem solved.

how long has it been doing it,if all very recent, then could be simple as bad gas,water plays very ruff in gas

I have a similar problem. I'm replacing the fuel pump and might get an aftermarket coil. The coil on my 5.2L Dakota is right behind the radiator on the front right side of the engine. Stupid spot! I'm surprised it hasn't melted!
The pump is driven by the timing belt so you basically need to take the front of the motor apart. It is quite a job to get at it but is doable. If you are going to do the job I'd suggest changing the timing belt, tensioner pulleys and the cam and crankshaft seals as well, may as well do some preventative maintenance while it is apart. I've got the whole proceedure and will make u a copy if you want.
