Car is running rough and has no power. Feels like it is missing also. It only has 63,000 miles on car. Someone told me it could be the idle air control sensor. Can someone tell me if this sounds familiar and help me with the problem.

---------This will help.Thanks.

do a compression test on the cylinders.If that checks out ok,change the spark plugs wires cap and rotor.The idle air valve on the throttle body could be working incorrect causing a low idle.clean the throttle body with a cleaner spray.

I had a 96 GMC 1500 with a 5.7 ltr. It would idle rough, especially on start up. After replacing everything under the sun, it turned out the ECM (computer) was shot. I found a used one and plugged it in and it ran fine. I think I paid 50 bucks or so for it. If you know someone with a truck like yours, plug theirs in and see if it fixes it.

Usually plugged fuel filters and/or bad pumps cause loss of power at the high end (full throttle) when you are sucking down the fuel not so much at the low end.

Rough idles can be a lot of things, usually something to do with the fuel mixture or timings. Dirty injectors, distributor problems, streatched out timing chain/belts... those are a few common rough idle issues.

Has the fuel economy gone down? Does it still have good acceleration?

Peace,

maybe coil pac!!!

check inj thay do click but not very load but becuase it might be it damaged it is doing this

change plug and wire if its been a while most cars have 90000 miles platinum plugs in them.but the wires wear before plugs.so change plugs and wires.+clean fuel injectors .change fuel filter and air filter.if car still run rough your idling to low.have idling check .

before you do this I would get some wooden qtips - the long ones auto detailers use. take off the air filtrer assembly and spray carb cleaner into the air\fuel intake and use the qtip to wipe out the inside of the intake. I had the same problem with my highlander a year ago and this fixed the problem.

Locate you computer (right front kick panel) and tap on it with a pen while the car idles... Also flex it back and forth with your hands to see if the car runs rough or quits... You may need a new one.
