Revs up while idling


If you didn't correctly reinstall the PCV hose from the black box at the throttle body back on to the valve cover, you might have a vacuum leak causing your high idle. I'd check that first. That is a common mistake to miss that rubber hose. It's hidden underneath the black box at the front of the valve cover. If it is loose, just loosen up the boot at the throttle body, and the two bolts on the right side of the black box above the valve cover. Reposition the 90 rubber hose back on to the valve cover and recheck it. A hissing noise with the engine running is a good indication that the engine has a vacuum leak somewhere- usually a rubber hose disconnected from the intake manifold or throttle body.

My 1992 chevy lumina z34 dies when I come to a stop sign.


I'm pretty sure your car has an "Idle Air Control" and this may be bad or the connectors to it could be corroded.

How do I change a in take manifold gasket in my chevy lumina?


remove the throttle body,remove the valve cover,remove the intake manifold bolts. you SHOULD be able to GENTLY pry the intake back enough to remove the gasket. be careful as to not scratch or ding any surface that comes into contact with the gasket.clean the gasket surfaces thoroughly and install the gasket. install in reverse order. make sure that you torque all bolts down to specs and in the order called for. on a final note...yu may have to remove the EGR valve to get some clearance to make it easier

DONT TRY TO USE STRAIGHT HOSE IT WILL KINK AND CAUSE NO COOLANT FLOW.WHEN YOU ARE DONE.FILL COOLANT BACK TO CORRECT LEVEL AND BLEED COOLANT SYSTEM.
