Turns Off in Low Speed

[windomino]

Hello All, I have a 2001 XLS and I am trying to find out what the problem is with my XLS because when I am in reverse in low speed or when I have slowed down and begin to accelerate slightly she turns off. Also she seems to be a slightly rough in the idle. Lets say when I am at a light waiting.

Strange indeed... is your check engine light on by any chance? Also you might want to check out the battery connections.

It could be the IAC valve. I had one replaced under warranty on my '01 XLS because it kept stalling.

No check engine light on and battery connection are good.

IAC, Should I clean it out or just replace it? Is this piece expensive ? Can this be done or should a mechanic do the work? Thanks for all the input.

Costs ~$60. Can replace in 15 minutes. Search for how to clean IAC. There is a thread explaining how to remove, clean and replace - with pictures!

I'd suggest trying to clean it first, but in my truck's case, it was a defective valve, and cleaning didn't help. Just FYI, my truck didn't throw a CEL either.
