Thank you so much for this post, especially the pics!! I am a COMPLETE novice when it comes to car repairs, but I also happen to be completely broke at the moment. So, when my 99 RX300 started not just idling roughly, but stalling almost every time we started it I of course panicked and started counting to coins in the jar on my dresser! :cries:
Thanks to your post and a $4 can of valve cleaner my 12+ year old beauty is running better than it has in years! I can't thank you enough!
For those of you who are contemplating doing this job yourself and have any doubts... trust me! If I can do it, most anyone can using this information and pictures! Go for it!
