Seems to have improved but it is my wife's car and I seldom drive it. She is out in it now and I am sure there will be a critique when she returns. I wasn't sure how aggressive to get with the cleaning process. I used Gumout (sensor compatible) and ran a soft brush through the throttle body and idle air control access chamber. Does the computer need to learn the condition or does it maintain memory? I disconnected the negative cable on the battery while cleaning everything.
Just how smooth does a PT turbo idle anyway? My guess is not very smooth but a confirmation would be appreciated.
