95 Tacoma with 2.7 liter engine High Idle Speed

1995 Tacoma with 2.7 EFI engine has high idle speed. When cranked cold idles at 800 rpm but as it warms up idle speed increases up around 1600 rpm. Does not idle down when clutch is fanned, have checked for vacuum leaks and have also checked most sensors. The exhaust manifold is cracked and I am not sure if this might be part of the problem. I am not convinced issue is not vacuum related but not sure of a definite way to resolve this question or issue, Any suggestions??

Re: 95 Tacoma with 2.7 liter engine High Idle Speed

That's a easy one lol. I just fixed the same problem today. It is your IAC. I thought my issue was lines to until I took the IAC off and saw it was not moving correctly. Rock auto sells one for 189.00 great deal

Re: 95 Tacoma with 2.7 liter engine High Idle Speed

If it is a dirty IAC, you could take it off an clean it. It's mounted to the throttle body. Coolant circulates thru it.

But it would also be a good idea to replace the cracked manifold.

You could just take it off and clean it but on that year they actually changed the denso sensor on it so its a good idea to change it
