I sprayed my intake with carb cleaner while it was running to clean it out and now instead of it idleing low, it idles high at 1200. I checked the throttle cable adjustment and it's adjusted loose enough. It's a 92 2.3, any thoughts.

Disconnect your battery for about 15min. That should reset all you settings.....

Tried the battery disconnect for 2 hours didn't change the high idle. Idle's fine when first started cold, but warm it idles at 1200. any thoughts.

Carefully look around in the engine compartment - you may have inadverently pulled off a vacuum line or electrical connector

I checked everything and it seems fine. When I cleaned it, I never even took the bottom part of the air cleaner out, just ran it at high idle while spraying carb cleaner in and now high idle. Any thoughts, maybe damaged the O2 sensor?

I don't think the o2 sensor, but maybe the catalytic converter ?

You may have knocked the intake flap out of alignment OR the OVP relay blew a fuse. I am guessing maybe the former. I am not sure how to adjust it but there is a procedure. With the car idling, take a look at the plate and see where its sitting.
