Need your input on what it could be?

I have been reading about the low idle and stalling problems that our vehicles have. My GS3 have been having the some idle problems lately and thought that it was either the "MAF" or the "throttle body". I've called my service manager at the dealership that I bought the car from and he tells me it's because of the cold weather we've been getting lately and that I should wait until next week to bring the car in if the problem should persist! Well, this where I need your input. Tonight on my way to work my car after the usual warm up period, still idles kind of rough the "VSC" and the "VSC OFF" with the "ENGINE" light stayed on even after I put the car in drive. What gives?

Need your help folks, and appreciate any input....

Doesn't anyone know?

27 views and no one knows what the problem might be? I guess I'll have to take it to the dealer and find out! Really didn't want to take off from work, oh well! Thanks anyways....

um check these out

From the previous threads about this. My Tech. at dealerships infrequently swap out the TPS sensor. Says that the way the MAS is set-up= problems sometimes
1) TPS sensor
2) TPS assembly arm
3) MAF
4) Throttle body cleaning or replacment

Good luck

Paul

Let us know how it turns out

Guess what it was?

Well folks after all said and done the verdict was a defective valve causing the #5 cylinder to have little or no compression. All covered under Warranty of course! Got the car back on Friday and I could tell there was a big difference. The check engine and "VSC" was working hand in hand, nothing wrong with the "VSC" according to the Tech. It was rough with out her for those 3 days, but the loaner I had( '03 ES300) made up for it, well just a little anyways. Sorry to rant and rave, but wanted to shed some light on my situation....
