Outer Limits 4x4 Board

Got a Idle problem
Some times it reves up to 1400 rpm
But most of the time it idles at 800 but is running rough and very fumey
At 1500 revs it runs great.
Any pointers would be great

The idle motor will be cactus. You can try cleaning the IAC motor with carby clean and also the throttle body but if the problem persists then you will need to replace the IAC which are available aftermarket.

This is all still assuming you have an injected v6. More vehicle info will help to get replies.

Sorry yes it is a injected v6 1994 auto swb NH.
Where do i get one aftermarket ?
I pull it out and cant see how to get it apart to cleen ?
