I've got a 1993 toyota 4x4wd v6 3.0 and when i turn on the a/c engine does not idle.

 

does it stall?

 

It does not stall. I forgot to mention it is an auto trans, in park when you turn on the a/c the engine does not idle up. Truck runs fine, it has 220,000 miles on it. The guy i bought it from replaced timing belt and trans .

 

Are you sure the compressor is kicking on?

 

Yes a/c is working fine, i had a/c company check a/c system when i purchased the truck. Ive herd that there is a idle up valve, but don't know what it looks like or where it is located in the engine bay. And is this unit adjustable?

 

Start here and go through the next couple of pics...

Went through pics, I noticed that the motor is a 4cyl., I'm running a V6, 3.0L motor.
