My wife bought a 2000 GT and everything was great until... we went on vacation for a week and when we got back it started making a loud humming noise when you'd start the car up ... all the way up into about 1.9-2k RPM.
I have
Cleaned the MAF (didn't appear to be dirty)
Replaced a bunch of tubing that was cracked and soft
Cleaned the IAC (or at least I thought I did)
used some throttlebody cleaner on the intake with a toothbrush
There is no check engine light... took it to oreillys and there were no codes.
I have not
Replaced the IAC
Looked at the intake manifold (not even sure what to look for here)
I have noticed that if I take off the baffle that connects to the IAC (this one: Little black box. What is this part?? - Modular Depot Forums) that the whining appears to go away.
Any other advice?
