Car idles high after warming up.

[joeym4130]

What could cause a high idle after warming up? The car idles fine just until the t-stat starts to approach regular operating temp, then she idles high and misses a bit. Any ideas on what the cause could be? Just throw some things at me to check..thanks!

i dunno if this matters or not but ima put it out there anyway. My car idles kinda high till it warms up, cold its at like 1200 then once its warm its at about 800. Just thought i would put that out there in case it can be of some use
