Was the problem present before you tried your concoction?

I would look for a vacuum leak first.

After using stp fuel injector cleaner and filling my tank the car started to idle at about 2500rpm and stayed that way after warm up. Should I try replacing the oxygen sensor.

I wouldn't replace the o2 sensor unless there is good reason. I doubt the STP treatment is related.

Should check for codes, if none present I would next look for a vacuum leak. I have seen the engine coolant temperature sensor cause odd things like this as they crack.

Good News.I really wouldn't have expected it. Must have been one heck of a lot of carbon.

I have a hard time assuming that because x happened that is is related to y. This was truley related.
