Ladies and gentlemen I have a 2002 ram 1500. 5.9 magnum V8. If you've already replaced your sensors as in cam aka pickup coil located in distributor and crank stop there. Reason why is 1 question. Did you replace your transmission. If yes let's talk about the flex plate. If it has the slightest bend then that's the problem. Some aftermarket crank sensors can be too long. You tighten it down and couldn't tell. I've dumped thousands into mine. Low compression cracked heads. I bought new heads timing gears and chain distributor spark plugs wires lifters and rods. So all that for a 20$ flexplate. As soon as I replaced it started the truck instant fix. No rough idle smooth as can be.
most likely its the throttle body sludged up . clean the throttle body and butterfly . this will only help if there is an idling problem . ck for codes and ck freeze frame data for more help
