The most common problem with high idle speed is a vacuum leak, Check the throttle body base gasket for a leak.

Where is the sensor on my 88 chevy 1500 that would make it idle high


Well there's not a sensor involved.
But the problem could be the idle air control valve, or a dirty throttle body that is making the throttle plate stick open.

Growling engine noise only at idle. Cam area


Take all of the belts off for a short run at idle. If the sound goes away it is pulley related, spin each pulley and listen for bearing noise, also check for play at this time.

If the noise does not go away when the motor is driving no accessories you have a more serious problem.

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.
