I'm at 97k and mine very well may have never been done. I've had it for the last 3-4k.
My AF learning 1 values have been in the 8-11% range. I did a vacuum test and it didn't show any leaks. MAF is next on my checklist... and maybe even an O2 sensor... but you can't clean those.
Thanks for the thread.
