I"m in the process of building up my 94 super cab. Axles, tranny, the works. Anywho, I have high idle, and yes i've searched the topic but cant really come up with any conclusions. Basically while driving around, when I pull up to a light and come to a stop, it wont drop from 1500rpms, unless I shut the truck off and restart, or tap on the gas a time or two or drag the clutch some to put a load on the motor. Most of the time one of those 3 work, but its still annoying as hell. And being that its not my daily driver anymore doesn't mean I am just going to say screw it and forget about it because I cannot stand when things do not work properly like they should. I'm getting to the point now after reading everyone's post that its a possible intake gasket leak on the rear of the motor, due to I have noticed a substantial amount of oil leakage on the back of the motor. But first, I can deal with an oil leak IF the gasket being faulty is not causing me to idle high. My question is, when I get a vacuum gauge, where do I check for leaks? What hoses per say do I check for vacuum? Every one of them? I'm also going to take off the IAC and put my hand over the holes to see if it idle correct or not because I read in a post by, I believe crazy white boy that he did this test and it turned out the valve was bad. If worst comes to worst, I'll tear down the top end and replace the fuel rail gaskets and intake gaskets but would rather check the easy stuff first. Thanks for all and any help/advise. Its greatly appreciated.
