My 02 galant running rough i replaced the plug wires on it bcause i mechinc said that was the problem but i have chaged out the plugs yet i noticed that one or two cyc. had oil in them when i pulled the plugs out . also i found a hole in my air duct hose and hear air but cant located it . when i put the car into gear it drops down and has lack of power to
Okay, lets start with the oil you found on spark plugs when you were replacing them. this oil is coming from the valve cover tube hole area, notice the plugs go into the holes in the valve cover, there is a gasket the goes around the top of the tubes and when it leaks it goes into spark plug hole, the valve cover needs replacing .
this will cause rough idle and running problems, after replacing valve cover gasket the holes must be cleaned, using crab cleaner, spray into holes and use air to blow out . this may need to be done a few times to get oil out .
after oil is removed . then remove spark plugs and wipe them clean.
The next step is to find the air (vacuum leak) , you said you hear it around intake tube. check for cracks or broken vacuum line. this leak will cause idle problems and driving problems,
Testimonial: "thanks i will do that i took to a friend of mine and he in turn took it one of his friends to put it on a dianostic test machine it had a misfire code he told me everything else was fine i have to replce my valve cover gasket but i will check that aslo and i have to replace my # 1 coil pack to"

If your car is running rough and it's fuel injected (which yours is). Follow the air intake (black plastic box - housing the air filter that has tubing that goes to the motor) until it reaches the Throttle body (rounded metal air intake at the end of the plastic tube - has one large flap inside). You will want to remove the hose clamp and thoroughly clean the throttle body and the AIC (air idle control valve - small canister attached to the throttle body). Use off-the-shelf cleaner from any automotive store. This takes about 30mins to 1hr depending on your skill level. This will result in a cleaner smother idle and smoother performance. This is a common issue in today's cars. I have to do this once a yr to keep my modified car running happy.
Take a look at the later parts of this article for pictures to give you an idea:

The EPC (Electronic Pedal Control) is the "fly by wire" system that controls the throttle, it took the place of the cable that went from the gas pedal to the throttle body on VW. If this light is on and there is also a P0102, MAF (Mass Air Flow) related code stored in the vehicle's computer, the EPC may be caused indirectly from a faulty MAF. If the EPC is on and there is no other codes stored, it could be a faulty electronic throttle body or need to be re-programmed. The vehicle's computer must recognoze the throttle body so when replacing it with new or used it will need to be programmed at the dealer. Recently I replaced a MAF (a common problem on VW's) on a VW Golf and when I cleared the code the EPC went off as well.
Check the engine codes, and replace or repair the faulty sensor (most likely the MAF sensor).

I suggest to get the codes checked so you're not chasing a moving target. You'll need to look online - check out the Ranger/Explorer forums - or get the Factory Service Manual (FSM) to get the technical info you're requesting.

SOURCE: stall out when given gas to excellerate ... runs fine in idle
For all those out there that have had problems with your Chevy Aveo Stalling, inconsistent idling, hard to start, or throttle problems, Hollywood Harv has the answer for you. Try a new Valve Idling Air Cont GM part number 93744675. You only need one and it has to be install by Chevrolet so they can place in the codes to make it work properly. Toss the old one away as most likely has so much carbon build up on the part that it stuck or struggling to function properly. It worked on mine after many different attempts at other stuff! This is a sure winner! Good luck and drive safe! Hollywood Harv
SOURCE: I have a 1997 Mitsubishi Galant with rough idle
I am having the same issue on Mitsubishi Galant 02. Clattering on acceleration, herky jerky idle. Pulled a code multiple cylinder misfire. My mechanic's diagnosis is bad valve cover gasket causing oil to seap into the spark plugs and bad timing belt, which I have not replaced at 150k miles. I do however know my fuel injectors do need cleaning, he hasn't ruled that out either. Have you pulled any code on it? I have read on engine knock sensor going out on some of these also. Hope this helps some.
