I have a 2002 Toyota Corolla with a very rough idle only prevenlant when the car is shifted in reverse gear-the car operates very smooth in all the other gears. I have changed the spark plugs, cleaned the throttle body, and checked for any vacuum leaks with no luck. Any ideas what this could be? Or where to look next?
have the same problem?
