Sounds like the idle speed control motor is stuck, this could have been caused by the cleaning.

SOURCE: low idle

Most often, dirty or faulty 02 sensors will throw off the idle. The 02 sensors and camshaft position sensor basically control all the idle. If TPS was dirty or bad, you would have some hesitation when giving some gas. Bad plug would cause lack of power or misfire.

SOURCE: 2000 FORD ESCORT WONT IDLE

on the sohc engine there is a rubber elbow on back of the valve cover going over to a line at the fuel injection that cracks at about 100K miles and lets the engine **** air and it will idle horrible til you fix it. Check this and see if it's not your problem...I've had it happen to 3 sohc engines and the dealer wanted $400 to fix the first one for my friend...Took about 30 seconds to pop the hood and pull it off, 3 minutes to glue it back together, an hour to dry, and 30 seconds to reinstall it...

The throttle linkage may be sticking. May have a vacuum leak at the intake manifold or with the hose connections.

Hight idle


Bad idle solenoid. Located on throttle body. It's black. Plugs in to wiring cable. You need a torx bit to remove. It's a cheap and easy fix. Also, get some throttle body cleaner and a tooth brush. Saturate the inside of the throttle body with cleaner and scrub out the black soot. Do this with throttle body in wide open position. Be sure to clean the edges of the butterfly good. They soot up and stick preventing throttle body from closing all the way.

What causes a rough idle on a 2002 chevy TB?


Disconnecting the battery sometimes corrupts the CPU program and it takes the use of a scanner to reprogram it . What you have done sometimes fixes the fault but like all CPU programs it only takes one bit to throw out the program.

Where is idle adjustment screw on 1989 nissan sentra


on the throttle body. the gas pedal cable from inside the car leads under the hood on drivers side to the throttle body. throttle body is attached to the intake.
*****you should not have to adjust your idle. itusually means that there is a bad sensor if your idle has changed suddenly,****
what exactly is the car doing? ex.fluctuating rpms?, low constant idle?, high idle?

Problem with electronic throttle control maybe. Any light's lit on the instrument cluster or messages engine power reduced . Could be a sign a position sensor is going bad . The gas pedal assembly has to sensors as does the throttle body . You could try cleaning the throttle body bore . Having a qualified repair shop hook up a diagnostic scan tool to view sensor data would be a good thing .

The oil pressure has begun to falter sometimes while idling, even causing the car to stop briefly.


The idle RPMs are probably too low because of a dirty throttle body, clean the front and rear sides of the throttle body thoroughly. Also, disconnect the battery while doing the cleaning, this will reset the computer and allow it to relearn to the newly cleaned throttle body.

Has low idle and wants to die when a/c is on when idling. Then when i accelerate, it sounds like it is shifting at high RPMs.


The low idle and wanting to stall is caused by a dirty throttle body, it needs to be cleaned thoroughly front and back sides using throttle body cleaning spray. Also while doing the cleaning, disconnect the battery to reset the computer so it will relearn to the newly cleaned throttle body.
