Just wandering if anyone else with the 2.2L has this problem.
When the engine is warm and I start it I notice that is will rev to 1500 RPM and down to 700 RPM. It will keep doing it untill I rev it up. then it will run normal.
Also I noticed that it will whistle when I speed up on city streets. Had the music off and heard it. happens most the time.

 

I can remember by having the rev problem once, so i didn't think much of it. The only noise I hear in mine sounds somewhat similar to a very muffled old VW beetle sound. That's the best way I can describe it. I think it is just the normal engine noise??

 

I must be one of the lucky ones...I haven't had any problems with my HHR. I would say if it continues to do that, to take it to the dealer and have them check it out. Of course...it won't do it then cuz it's been running.

 

The noise is from the front of the car. It will go to the shop.

 

are you sure the whistling noise isn't from the a/c being on outside air instead of recycled?The car switches to outside air everytime you start the car.Thats the only whistling I have heard out of my 2.2. No idle problem either..

 

I'm sure. I don't hear it unless I have the window down. It almost sounds like a turbo.

 

So far, other than 1 problem with my remote start, the only other problem I have had is paint. Mine starts fine and has never revved. Keeping my fingers crossed.

 

never a problem here

 

I had a problem with my 2.2L 5 spd this past weekend. My problem was keeping up with CJ. lol. Damn, CJ! You can freakin' drive the hell out of that automatic.

 

Too funny.
