ASE Mechanic:
did you replace spark plug wires? If so I would tend to think that may the wires got mixed up, common thing for a doityourselfer to do. I have done it too!!!!!!! But a IAC cleaning is only good for a small rough idle. To me it sounds like something else is still wrong. Check fuel pressure and volume, if that was the first fuel filter since the car was new you might looking at a fuel pump, and fuel pressure regulator. Sometimes too that coil pack has issues with the ignition module. make friends with local parts guy, sometimes he takes returns.

Check the IAC Idle control valve. See if cleaning the valve will make a difference. Buy some carburator cleaner or brake cleaner.Take off the air cleaner duct work that goes to the fuel system. Look inside the hole going to the fuel sytem. You will see some holes on the cylinder sides. Two of these holes are the IAC Valve. With the car running at about 1200 rpms spray the cleaner aiming straight into the the holes on the side. Give it a good ten seconds of spray. next, turn your engine off and let the cleaner soak for a while. Repeat the process a few times. This should clean the valve. It can also be removed from the side and cleaned. If cleaning does not do the job, replace the IAC. Hope this helps you.

I have a 99 Dodge Ram 1500 v8 5.9 it's running really bad and when you press on the gas it bogs down and dies out it also rattles and bangs and barely runs

Check for vacuum leaks with a can of carb spray. Replace fuel filter. Check fuel pressure. When was the last tune-up? Plugs and wires.

typical maintenance. (check the manual)

I have a misfire with no eng light on car runs crappy then runs good then crappy

what year car?
what location, ? many engines used world wide.
how many miles on car? 60k or 600k?

ever do a full tune up, if not why not?
spark plugs, filters. read the operator guide, its in the glove box.
misfire is complex and 50 ways to get it.
but can be broken down to.
1: lost engine compression.
2: bad spark (tune up)
3: bad fueling (tune ups replace fuel and air filters. so...)

No problems really,stalls once in a while. Just curious what consists of a tune-up on my engine. what I should replace and so on.

This would include your spark plugs or coils, the wires, a new distributor cap, an oil change, air filter, fuel filter, and a coolant flush. A tune up can make a car run like new again. Some don't change the fuel filter on a tune up but I have always said it is best too. They can get clogged up over time.

Have you had a tune up recently? air filter, fuel filter, cap, rotor, spark plugs. Maybe bad gas " water in the fuel " Check fuel system, ignition sytem, air system. Get a diagnostic test performed at a reputable shop.
