I have post on here a few times,and still need help,about the idleing too high
When I took the old IAC unit off,I stick my finger in the insert and it is black.,should it be clean ?,if it does,what cleaner do I use ?
just clean it with a rag. You could clean it with anything.
CRC makes a air flow sensor cleaner spray. It should work on a intake air temperature sensor. You could also try electrical contact cleaner spray if you can't find the CRC stuff.
The high idle speed could be caused by a vacuum leak. It could also be a sensor. Try getting the codes read to see if any codes are pending.
