Hi all, My GAGT has had a "bobbing" Idle lately, usally when I start it up (cold or Hot doesnt matter) it will "bob" between 500 and 1000 RPM and when I rev it up it usally stopps. I cleaned the IAC valve and reset the computer and that helped for a week or two but its up to its old tricks again. Any suggestions would be greatly appreciated thank you for your time...

Could be a slow IAC valve, or a o2 sensor acting funny.
