Question IAC Valve?

Morning folks,

I have a quick question. What are the Cons to unplugging the IAC Valve?

I've been havin intermitent loping, shuttering and rough idle. In fact going down the highway yesterday I stalled out 4 times going between 40-60 MPH.

My CEL came on and is still on.

I unplugged my IAC before I left work this morning and is running beautifully!!
(My idle is now around 1.2K instead of the usual shuttering 900.)

However, my CEL is still burning an impression into my bald head!

Questions, querries & posers are all welcome.

Welcome to the forum.

Were you expecting "posers" to respond?

The IAC can never cause the engine to cut-out on the highway, unless the throttle was in the closed position.
IAC problems don't cause misfire and stuttering - a bad IAC/ISC will cause eratic or incorrect idle speed.

I suggest that you check the plugs, coils and HT wires - the standard plugs are best suited and set these to 0.030" (0.75mm)

It would help if you got the error codes read and post them here.

Cheers, Ron.
