My Mustang has been idling very inconsistently now that the weather is getting colder. After the car warms up, the idle will be from 500ish to 800ish and bounce in between those throughout the entire drive.
When coasting in neutral it sometimes will hover at 800 or so consistently, but usually it will bounce in the 500-800ish range.
The driver side exhaust manifold has a very minor leak, at least it sounds like it to me.
Also Im running a Strategy 87 tune from SCT (the preloaded tune, not custom) and I have a bunch of bolt on mods. I feel as though I need to get a custom tune to really get the car to run better, but I'm not exactly sure about that.
Ive cleaned the TB, EGR, New IAC, adjusted TPS
Bolt ons: CAI, TB, Plenum, X-pipe, and Magnaflow catback
Really Im asking if fixing the exhaust manifold or changing to a custom tune should help me out. Or if its something completely different!
