I have a problem with my1989 gmc suburban, the idle is set way too high ( apx 2700 rpm) where is the idle adjustment screw located on the carb?


there is no carb, and no adjustment. if it idles too high, there is a vacuum leak, so check the large hose going from the base of the throttle body to the valve cover. if thats OK, these are known to have a leak at the base gasket, usually at the rear of the throttle body. spray carb cleaner around the base and see if the idle changes, if it does, replace the base gasket.

Where is the valve idle air control on 1996 chevy suburban


if you follow the air cleaner/filter tube to where it meets the motor you will find the throttle body and it is mounted in the throttle body on the opposite side of where the gas pedal cable mounts. it has a 4 wire plug i believe.

How to clean 2001 chevy suburban 1500 throttle mechanism


Buy a can of Throttle body cleaner and follow the instructions on the can, make sure you buy Throttle body cleaner. Carburetor cleaner is to corrosive to the gaskets used in the Throttle body's. The basic way to use the Throttle body cleaner is to just spray it into the Throttle body, working the Throttle blade and making sure that you also clean the Idle Air Control passage ways. As long as you follow the instructions on the can, you will have no problems. Just note that different Throttle body cleaner products will have different instructions, so read before you use. Just pay attention to the throttle blade, it's common for Carbon to build and can cause the blade to stick from time to time.

Good luck and keep me posted.

Vaccum hose diagram for 88 chevy truck. I put a 350 motor in my 88 chevy 1500 truck from a 95 suburban. I cant get the throttle body to stop idaling to high. I may need a vaccum line diagram for this motor...


it may not be a vacumn leak from a line,check the throttle shaft for movement,for example,i had a 89 1 ton 350 and my throttle shaft was moving around a lot and in order to keep it from idling high,i had to kick the throttle pedal.But also check the idle air control valve,which is the round sensor on the side of the throttle body.

It will take a few miles of driving for the ECM to catch up to the new throttle body. Assuming it was an OEM replacement, its cleaner than the old one, so the air flow is different. 20 minutes of driving should do the trick...if it doesn't then you have a different problem.
