high idle on starting is normal as it is the same as a choke being on. When it drops back it should be around 900. However tacos in cars are not real accurate under a 1000 rpms so have it checked manually with a rev counter. Run the fault codes to check for a problem.

1100 to 1300 is normal on a cold start. May want to see if a vacuum leak has developed or if the throttle plate is sticking open when it is cold.

If you have not run the fault codes then that would be a good place to start. It will save you money as it will pinpoint the failing sensor.

A manual transmission is about 400 RPM and and automatic is about 700. When you put the automatic in gear it will drop by about 200. When the engine is cold you can be about 1100.

Hi Joseph, When starting the vehicle from cold in cold weather, the RPM can be as high as 1300 and in temperate climates about 1100 RPM. The RPM will drop to normal as the coolant is warmed. Normal idle speed is between 750 for Auto and 650 to 700 for manual transmission. Regards John
