2012 Mustang GT Manual - rough idle/revving/stalling
Hello! I have an issue with rough idling, revving when in neutral, and intermittent stalling when in neutral. Specs are:
2012 Ford Mustang GT/California Special
Aftermarket cold-air intake
I have tried cleaning the throttle body with throttle body cleaner, cleaning the MAF sensor with MAS cleaner, and tightening the intake hose to ensure it's stable and airtight.
Has anyone else had this problem? Any fixes?
