Ok I cleaning my maf sensor and decided to clean my iac valve(side of the throttle body, held on by bolts, not screws) well I cleaned it and every since then my car has a lopey idle like I was running a bigger cam...the gauges do not not bob around or anything...it doesnt drive bad or choppy..it makes the car rock back and forth a little at red lights.all of this doesnt really bother me but Im just curious as to why....btw I used contact cleaner on it
