Code 35 will NOT go away!!!
 

Code 35 is for the IAC valve. I have replaced the valve itself, the harness that plugs into it and cleaned up the grounds on top of the upper radiator hose on my 4.3L.

The "cure" for a code 35 is just supposed to be (replace IAC).

Im just short of getting a new ECM.

Any help before I hopefully dont waste some more money??!!

:mad:

Did you do a relearn on iacv? Also clean port good where iacv goes .. may have some gunk not letting pentel work right.

Don't throw your money on an ecm, sensor or needs cleaning ect.

Resolution
 

I forgot to mention that i had my intake manifold gasket rerplaced, the mech that did it DID NOT tighten down my distributer when he put it back in. so through a chain of sequences it was the timing.
