25 Idle air control motor circuitstarget idle not reached (+/- 200),vacuum leak found
52 Fuel system rich

At least its not lean lol

I would look at all your vacuum lines first off and make sure there nice and snug. You could even clamp them to be extra sure, but the hoses are usually pretty tight on the fittings anyways. Check that first and tell us what you find.

I don't recall what you can spray on the lines to see if there leaking, I believe its propane or something similar. And it will increase your rpm's from an idol stand point if it is infact leaking.

Be careful,
Sean

I would seriously think about going down to the parts store with everysingle vac line that in your motor and spend the 20 bucks to compleatly re-line your car... for 20 bucks I would do it...

your probally running rich due to the vac. leak thats causing the iac sensor to read more air so more fuel... hence the rich condition... is your tb plate sitting flush and compleatly close???
Is your tb compleatly tight with the gasket... how about your intake manifold gasket???
