You can manually operate the IAC valve with a 12v source.
Google "IAC test tacoma". I'd close it, leave it disconnected, and see if that solves the high idle. If not - suspect vac leak.
If so, reconnect it and see what happens.
I will try that today (this weekend) after I get my shops new lights up and wired.
Between that, work and my son's Eagle project I have had very little time to look at the truck.
I know I unhooked the plug but it is still stuck at this point.
Thanks fo the input.
I have a second question, this one is on the linkage.
Someone said "Don't use WD40 on it" ... I read that the day after I gave it a squirt.
This is just on the outside linkage, does anyone know of ill effects from the WD?
I may be pulling it completely off and giving it a good cleaning and reasseble.
I ran into another write up about linkage wear and adding a washer to acomidate it.
But that is getting ahead of myself, I won't know till I get a closer look.
Thanks for the help
