Hello I have a 2006 Malibu SS and since I bought the car I've had a rough idle/miss, they finally admitted there was a misfire and had to replace the heads on the vehicle because grounding compound was left inside the engine. From the day I picked it up it still rough idles and misfires but each time I take the car in they say it's fine. All you have to do to see the problemis lift the hood and put your hand on the engine or look at it to see it's misfiring. I plan on being there this time and showing him the engine and how far down the tach drops. But are there any other indicators I can point out to him to help my situation.


TIA

James

 

I'm interested to here what comes of this. My '07 has a bit of a miss, but nothing I can't live with. And it's only during idol. Under power it runs glass smooth with no hesitations.

 

never had any idle issues with mie, but I had it flashed couple months after I got it, mine RPS drop at idle if my fan kicks in on warmer days, not so much today, with -28....WOOHOOO LOL......
