Im wondering if you can answer these questions. It's my first time here so I will try and include detailed stuff abiut my Truck.
IAC (Idle Air Control)
After taken the IAC Valve out and cleaning the black residue at the end, I'm wondering how far the end of it should be going in/out? I tried turning the car over with that valve out, and all that happens is a small movement- Is that normal?
Also I see some really small holes at the end of the Pintle, Should those be really clean?
How would I test the IAC Valve? I do not have the money to take it to the dealer at the moment, Just had a new baby!
Is there some easy way to check it?
One thing I did do is to test the resistance of the valve and things checked out ok.
Should I replace the small "O" ring? Is so where would I get it at? I checked online with no luck.EGR VALVE
*How would I test this with the valve attached to the engine? A mechanic
a while back cleaned it, but once done he did NOT use a new gasket, he resused the one it had on it. Is that very important to get a new gasket?
when recently replacing the fuel pump, did not put a new rubber gasket when attaching the assembly back on, he just reused the old one.
Should I get a new gasket an dhave it put on? Is it very important or critical?
