But if you request things be replaced, and that doesn't fix the problem, it will be all on you, and dealership prices are a bit high for rolling the dice on if you get my meaning.
I'd find a backyard mechanic before running that risk.
I have a 2006 Grand Cherokee Laredo 3.7L and am having idle issues. When I'm sitting at a light and the car is warmed up (driving for about 30 minutes) it will sit at 600-700 RPMs but then will drop to 300-400 for a second or two and then catch itself and rev back to 600-700. Also, when I go to take off after stopping, when it shifts from 2nd gear it will have a shudder/hard shift but shifts fine other than that.
I have repeatedly expressed my concerns at the dealership with no avail. They seem to know what the problem is when I take it in, and then they call me and say nothings wrong with it or they couldn't get it to duplicate it.
Anyone have any ideas? I've read it could be the TPS or IAC but don't know if they would replace those if I requested them too.
