wire tuck set back.. high rev.. help!
Ok the car is done and everything is moved except the battery. When I start the car, right off the bat it just starts reving higher and higher.. it seems to stop at a point but when I rev with the gas it goes even higher and then goes back to where its reving itself. what in the hell could cause this? Anyone have a clue?

Then you have a vacuum leak somewhere - IACV, brake booster, vacuum lines, intake manifold gasket, bent throttle plate, etc. You have a simple problem with a few potential causes - just methodically go through everything and find where the air is getting past the throttle plate un-metered. Your throttle cable isn't over tightened is it?

The only wires I Cut and extended were headlights (high and low), corners, bumper lights, the two little wires that run to the brake booster, horn wires, radiator fan, extended the wire from the positive terminal to the fuse box. That's it pulled the fuse box and harness cluster on the pass side into the car tried to start it.

Well I did disconnect the hose that goes to the brake booster to the back of the manifold and if made a sound like a lot of pressure was released after I heard the the I twisted the pipe coming from the mani downward w. Rubber hammer then ran the brake booster hose to it to hide that but before this it ran ok, throttle cable hasn't been messed with same as the intake mani gasket, it was fine too. My vacuum lines look good nothings left without a hose or unplugged. I also disconected the hose that runs from the intake manifold up to the iacv and souded like I released pressure too. -_-
