2000 L-Series 2.2L Sedan
Default (Saturn 2000 LS1 Manual) Idle Issues?

For lack of a better way of putting it, my car is pushing the gas on it's own when it starts idling around 1000 RPMs. In order to make sure I wasn't imagining it, I put the car in first, let off the clutch, DID NOT TOUCH THE GAS, and the car DID NOT STALL and started driving very slowly.

Regardless of which gear the car is in, after pushing the brake, the car speeds itself back up to idling at about 1000 RPMs, about 5-10 MPH.

We have cleaned the throttle body and replaced the throttle position censor. It was a warm day and seemed to "fix" the problem to the point of doing the same thing, but at a lower idle speed. At this point, the person riding in the car with me told me that was normal. But my car has not done this in the 10 years I have owned it.

The very next day, the temperature was very very cold, and the car started "pushing the gas" on it's own at around 1100 RPMs. After the car warmed up, it dropped to about 800 RPMs before the gas petal would push itself in.

It was suggested that the Idle Air Control Valve may be to blame because the weather seems to affect the issue.

Any suggestions?

Thank you in advance for any insight you can provide.

REWARD EXCELLENCE!

Mileage, maintenance done, parts replaced? More info helps paint a picture for everyone that doesn't know anything about your car.

When warmed up, where's the temperature needle positioned? A worn out thermostat running cooler may be causing the engine to remain at higher idle rpm compared to an engine operating at ideal coolant temperatures (185F-195F). There's a direct correlation between coolant temps and idle rpm; cold engine starting usually has higher idle to prevent stalling with required rich fuel mixtures that would stall engines running at normal idle rpm. As coolant temps rise, less fuel is needed and rpm's drop gradually until a fully warmed up engine idles at normal rpm - all within 10 minutes of driving. A worn out t-stat may allow cooler operating temps that the keeps the idle rpm's higher than it should be.

Default Re: (Saturn 2000 LS1 Manual) Idle Issues?

During cold start is when the car is having issues. I paid more attention to the RPMs yesterday, and every time I hit the brake, the RPMs went up before going down again. After the engine warmed up, the weird idling stopped (for the most part). The temp gauge is reading about 5/8 after the engine fully warms up.
The car has about 168,000 miles on it.
(Not much time to respond atm, is there any other information that would be useful?)

Also, the car is now "pushing it's own gas petal" around 1100-1200 RPMs. The issues seem to be getting more "in depth" as the days go by.

The only part that has been replaced so far in trying to fix this issue is the throttle position sensor. And the throttle body was cleaned.

In addition to thermostat problems, did you ever replace the original coolant sensor? Original ones are fault prone round nosed and plastic. They fail by running rich and higher idle while never sending correct temperature signals to the pcm to determine when to turn on the cooling fan. The permanent replacement is a flat nosed brass sensor.

If pressing on the brake pedal affects the idle rpm, then there could be an issue with the brake booster (diaphragm leak). Try disconnecting and blocking off the vacuum tube at the booster. You could still drive the car for a short test, but be warned that it will take much more pedal effort to stop the car (don't go very fast). Some of us remember what is like to stop a car without power brakes. Both feet on the pedal works. If the problem goes away, then you need a new booster. Fix it.
