sup guys just joined ur site.. anyways i have a 2000 5.9 4x4 durango that i just purchased and noticed it shaking and the engine light came on well took it in and #2 plug was misfiring took it out and yea it was a bad plug but replaced all of em to make sure... well seems to have a bit more power now but its still idles rough and still has a shake to it and also it will shut off if ur sitting at a light and or just driving down the road and wont start till u disconnect the pos batt cable and connect it again and it will start.. but shouldn't the idle jump up when the a/c is on or goes into gear?? it stays at 600rpm. it runs fine when just cruising fine besides shutting of sometimes.. the cap,wires and plugs are all new but i never checked the rotor... could it be the coil pack going out? let me know please much help is appreciated thanks.

Clean your IAC out.

Matter of fact, take the throttle body off the intake, remove all the sensors and clean it very thoroughly, get all the gunk and crud out of it.

When you clean the IAC, don't scrub it with anything, just hold it with one hand, and spray it down good with brake or carb cleaner.
