High idle in reverse


I had this same problem. You will have to replace your mass airflow sensor.

On a cold start i have no high idle for warm up


coolant temp sensor and intake air temp sensor would be the next to check.intake air temp sensor is in the air intake tunnel between TB air air box. when running is there a DTC? by disconnecting the coolant temp sensor you put the ecm values at default try that if it corrects your issue replace it.(it will turn your check engine light on but you can clear later by disconnecting battery)

My 2.0 engine idles fast on a cold start. Then idles down after warming up.


This is normally the way it is suppose to work. You need to have the RPM measured for High RPM and duration. What you are describing is how an electronic choke is suppose to work.

The errors would be how high the RPM goes and for how long it lasts. When cold the RPM, fuel mix and timing are changed to give a rich fuel mix. As the O2 sensors warm(Could be defective) they signal the engine to lean up. The water thermostat also has something to do changing the engine to a lean running slow condition.

If obtaining heat from your heater seems to take Forever, the thermostat could be weak. This would coincide with the engine continuing at a high RPM longer because it is not warming up.

My 2005 ford focus is running at a very high idle, or a vacuum leak. How can I tell which one it is? And how hard or how much will it cost to fix.


Quite possibly a vacumme leak. check all around intake manifold for vac hoses disconnected and /or cracks where they connect either to manifold or trace to end location and chec there also

Where is the vacuum modulator on a 1989 Chevy silverado 4x4?


Have you tried to adjust the idle itself to bring it down? The adjustment should be right on the throttle body where the gas pedal is connected to the throttle body. There should be a screw that will allow you to adjust the idle up or down. If you loosen the screw it will take your idle down

I have a 2005 ford focus 2.0L it has a mis at idle but runs fine going down the road.PS I changed the control air vavle


are you sure it is a miss or a vibration? Focuses are famous for a vibration at idle because of the upper motor mounts. some get so bad that the whole dash vibrates at stop lights.

My 2005 trailblazer idles real high all the time


Check the cheap plastic vacuum reserve tank; if this is cracked (or any hoses attached to it) you are drawing in air that spoils the fuel-air ratio and this will produce a lean burn.
