Really High RPMs on Startup..
#1
..I've been getting really high rpms (~2000-2200) on start up a couple of times..... and when this happens it normally does not come down... I restart the car and it is better....
Does anyone know the cause for this???
Thanks in advance

How would I confirm a bad a/f ratio or the bad thermostat....???

2200 RPM is not abnormally high for cold engine startup. However, if the engine speed at idle doesn't come down from there, then that is something to correct or have corrected.

I believe my normal start-up rpms are usually around 1500 dropping down to about 1100 until it gets to operating temp...
However, when this happens it shoots up to 2200 to maybe 2500... only has happened a few times... And it doesn't come down. It appears as if it gets stuck at that rpm....
what could be causing this????
