yeah, your iac motor is messed up. try recalibrating it so it will close a little and shut your idle back down to the right rpm.
Having Problems? Heres my Three step solution to anything 2gnt related. Step 1: Put down everything in your hands. Step 2: Grab a lucky strike, Smoke it. Step 3: Walk to the fridge, double fist some keystone ice, sit down in the shade, drink one beer, finish cigarette, drink other beer, roll a joint, smoke it, walk back to your problem, and in about 5 minutes the solution will come to you. If not. Go here: here
If still nothing, your trying to hard. Start over at step 1.

"calibrate it" i have no clue what he's talking about. it might have just gone out for you, CEL 25 is the IAC motor, regardless of if its clean or not, its not functioning properly. either replace it or pull it out and give yourself a throttle body service (clean the tb real good with carb cleaner) same thing happened for me but started with a lumpy idle, i pulled the motor off, hosed the TB with carb cleaner, cleaned the IAC REALLY good, through it back in. wah lah. you can also always replace it.
