Not better - Worse
So I cleaned out the IAC with Carb Cleaner, let dry, and reinstalled last week and it seemed like it removed the problem. A few days later the stalling came back, and today my O/D Off light started blinking. From what I've researched it looks like I really should have replaced my IAC gasket even though it looked fine. Could this be the cause of the O/D Off lighting blinking, or do I have more to worry about?
