Howdy All - I'm going through a smog checklist in an attempt to get my 83 4x4 pickup on the road again.
I can not get the EACV to operate like i think it should. In essense it seems like a pretty simple device -->air comes from the smog pump and goes out one of two ways. 1 - to the exhaust manifold, 2 - to the air intake. Problem is I can't seem to get mine to switch to the exhaust manifold even when i apply current directly to it!
I have been looking everywhere for a replacement EACV but nobody sells them! Even at the junkyards they seem to go before anything else. So 3 questions:
1. What are the proper test procedures for the EACV
2. Where can i get a new one?
3. Will something from another vehicle work? If so which vehicle.
