IAC questions I have a 2001 WS6 that has been idiling too high for several days after the engine was driven for 20 minutes or so. I cleaned the MAF. I removed the IAC and cleaned the end of it and the area inside the TB where it goes. Is there any service that needs to be done to the IAC? Do I disassemble it, push it, pull it, twist it to clean it? I thought I had it fixed yesterday but this morning it started idiling high again. Do they go bad?

No warning lights at all. I filled it up on Saturday (always 93 octane) and drove it on a trip that was longer than my usual drive to work or around town. I didn't drive it on Sunday and it started acting up on Monday morning.

I can't find a vacuum leak anywhere. This always happens after it's warmed up. I found out yesterday that if I turn the car off for about 30 seconds and then restart it, it idles fine again. Drive it for a while and it acts up again. Could it be the TPS?
