Question about Cars & Trucks
Had it to dealership a couple of times,they tell me it's the character of the engine because no codes are showing and all cylinders are firing. Now it*s getting worst.
A somewhat rough Idle can be usually found in a three cylinder car, thats okay. can it be tuning? does this happen with the AC on?

Testimonial: "I have a 5 cylinder and yes it happens when ac is on.the truck rides perfect on road but at idle it is rough more so in drive or reverse,it vibrates really bad ."

I had the same problem. Have it checked at an checkers with one of their computers. I had a multi misfiring. I changed the ignition module on it. It runs great now.

Clean throttle body first, make sure you disconnect battery foe about 30 minutes so PCM can relearn to cleaned throttle body.

If your engine light is on, please get a free scan at your local parts chain and send us the trouble codes. Recommend you start by removing the idle air control valve and cleaning the valve and passages as well as the throttle body with carb cleaner. Check the operation of the valve by hooking up the connector and turning on the key (do not start the car) while it is off the engine to see if it actuates. Please let me know if you have questions.
