Hello!
My 2011 mustang 3.7L has been having a rough idle issue for a while. If it’s getting any pedal at all, it runs normal, good power/acceleration, normal, with mpg up to 30 miles per gallon. But sitting idling, it may idle smooth for a minute, but it’ll get rough, and buzz a bit. It throws the P0023 code, so I replaced the drivers side camshaft position sensors with no result. Lights dim slightly from time to time, so I had my battery and alternator checked. What’s going on? I saw some people saying there’s a solenoid in the alternator that can act up, could this happen in a way that doesn’t show easily on the test? Could it actually still be the alternator? This has been going on for about six months. Thanks!
