SOURCE: How to locate idle air control valve?

It's located on the left rear of throttle body assembly. I looks like a small metal cylinder with two bolts and an oval plug with 4 prongs. Yes you can change it yourself. If you can't find it, go to your local auto parts store and have them show you a picture.

My 97 chevy lumina recently started to idle high it will actually drive itself shifts hard and not into every year and only my right front brake works


The high idle problem could be a stuck idle air control valve or a major vac leak. Something like the vac hose going to the power brake booster for example.
The computer controls idle speed with the idle air control valve.
Extra air may be entering the intake beyond that control valve.

I purchased a 1997 chevy blazer ... looks great interior and exterior... but when I drive and stop, i have to keep 1 foot on gas pedal and one foot on break. what do i do ?


Here is the common cause of surges, cold stalls, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours.

To correct this problem get a can of throttle valve cleaner (it is made by CRC) from the local auto parts store, spray it into the air intake of the engine until you have used about half the can, you will need to hold the idle up while you do this, it will try to stall, after this shut the engine down and disconnect the Negative (-) battery cable for 5 minutes. The intake is know clean, if you continue to have the stall out the idle speed control valve may be defective and requires replacement.

1997 chevy malibu 3.1 engine starts rough and wont idle only runs with gas pedal being pumped


check the fuel filter to see if it is getting clogged and not letting enough fuel through it. make sure you have proper fuel to throttle body so it will run properly. if this does not help much, check idle air control valve.
