At stop lights, the rpms will shake at 1000rpms. I believe thetexhaust has a weird smell to it...like burnt...something...not necessarily burnt oil. But, then again who knows. Symptoms generally only happen after cold start and just the once at the begining of driving..except rpm shaking...that happens at every stop..but not if in park. I checked the oil and tranny fluid Both are fine. Had oil changed like 1500 miles ago. I'm hoping this is a qauick fix and I won't be **** out of luck. Please if you have any ideas or experience...lemme know. I bought the car new in early 2010. I haven't had a tune up, I only have 15k so ya know...figure not necessary
