Thank you for the detailed instructions. My 2000 rx300 has had some rough starts within the last month and I decided to clean the iacv before it got worse. Did it today with no problems other than stripping two screws. Managed to get them off with vise grips however I think I should replace the screws someday. Hopefully for a long time, I don't experience the sudden shut off when I start my car. My rx300 has 310,000 miles with little maintenance on my part. Runs great and I hope it will stay this way for at least another year. Thanks again!
