I'll have a good look at the wiring again- and report back.

OVP is about six months old. The more I think about it, the more the wiring issue could be it??

Stay tuned and thaks for your help!

Didn't wade through all the answers, so ignore if this has been answered. In regards mounting the ICV backwards, I did this, and for no reason I can think of, it did not run right. Idle was erratic. Correcting airflow direction solved that. Arrow should point toward the intake manifold, away from the airflow meter plenum.

OK lets wrap this one up:

After again taking the OVP socket out of the bracket which it sits in- and found one of the wires going into the socket (large black) had worked loose. This wire was still in its connector (which then slides into the socket or base) but the solder was gone. It looked fine the naked eye and even measured fine with voltage (pin 30 I believe but don't quote me) however once running it was wiggling around causing all sorts of problems with ABS/ICV and who knows what else.

Once this bad wire was properly secured and reconnected- the now reconnected ICV functioned properly allowing me to lean the idle mixture from stupid rich- lowering the idle speed (600-750), then allowing me to measure and fine tune the idle pot.

Although I can only get the idle pot to read 0.81v, and still want to fine tune the idle mixture- everything on the engine is connected and functioning.

Bottom line:
Don't chase one problem with another, go slow and try to diagnose problems one at a time. And listen to others here on the board!

Thanks all for your help (especially simmo300E and Bruno_300TE)

I tried to adjust idle mixture to compensate for a slightly off idle. Now 300e won't start and I was very frustrated until I ran into your thread.

Will try your solutions and thanks a bunch for the crack up.:P Great thread!!!
