idle drops, inptu and help please ok i've got no codes coming up. i'm thinkin vaccuum leak because when i come to a stop my car's idle drops to 500 when my foot is on the brake but when i take my foot off the brake and pull the e-brake or just put it in nuetral the idle sits at 600 . . . i'm gonna pull my manifold next weekend and replace the gaskets and make sure everything is hooked up in the back of the manifold. any other ideas?
things i'm gonna do tomorrow: oil change, fuel filter change, empty my gas tank of that crappy Raley's gas and fill with chevron 91 and add in fuel injector cleaner. i've pulled the air filter and it's clean, so is the MAF and everything visible is plugged in. i'm really hoping it's the gaskets never got sealed properly underside of the manifold.

check the air lines from the manifolds also, and any vaccum line also. might also check your EGR seal also.

pull it, wipe it, leave it unplugged, turn the car on 10 seconds, off again, on, then off, plug it back in, and see what happens, will have to re-learn... I didn't clean mine up when I did my TB swap and have been having my idle drop at times when I come to a stop, it's intermitent though, doesn't happen every time until after the engine is warmer, but its a good bet thats what it is
