It shouldn't need reseting? Probably controlled by the PCU (Computer)
By farting in the gas tank.
Had the same problem w/ a '92 lumina a couple years back. the car would barely idle and stall or idle and pick up speed until it got to like 30. forget what the part's called, but it gets clogged up and just has to be cleaned out. not too expensive. guess its common w/ luminas and cavaliers
1990 gmc p/u 5.7 wont idle showing code 12
Is this a 3.1 liter engine? tipicaly by the throttle body area. idle sensor or idle air controll valve?
the thermostat will make both fans become idle if it is not opening. this happened to me on my 95 3.1 lumina
It is very possible that the throttle plate is dirty and causing the throttle to hang up.
On a 2001 Chevy Lumina with a V6 engine, the high-speed idle control is typically managed by the throttle body assembly. The idle air control (IAC) valve, located on the throttle body, regulates airflow and adjusts the engine's idle speed. You can find the throttle body on the intake manifold, near the front of the engine, connected to the air intake system.
If the idle is too high, it is likely the Throttle Position Sensor (TPS). If repeatedly stopping an restarting the vehicle solves the issue (temporarily) then the TPS is the problem.
Could be you need a new fuel idle motor. Or you need new spark plugs
My 1990 idles at about 850 and with the ac on 1100
time to replace the pump and rack and pinion sector
It could be the Idle Air Control (Idle speed control) valve. Its located on the left side of your TBI and has an electrical connection.
