Issue @ Idle...
So for a while now I've been having issues when my car is idling in gear (red lights and such)
Whats happening is that I can feel the car getting a little shaky, Very little, but noticeable. along with the rough idle, the car starts running lean, but goes back to normal if I throw it into neutral or start to drive.
Now there are time (few and far between) that the car REFUSES to settle its AFR for a while after setting off again.
Has anyone had this or similar issues with their GT?

Had trouble with mine this week idling rough; fuel trims were -7...-10 and +10 at WOT. My installer (Rick Crawford) thinks it's the MAF card as everything else seemed OK. Might be the same for you but I'm just going from my experience. New one on order for me and should be in early next week if not tomorrow.

Or something with the evap purge. Check for vac leaks around the connections of the evap purge to start with I'd say.

well I cleaned the MAF and the TB, checked for vac leaks and re-fixed a wire that was going to the MAF sensor (fixed in the past with tape only) still the issue persists.
Anyone have another idea?.

Is it possible that the issue can be something to do with my tune? I never made any changes previous to the issue starting, but I had one guy tell me that sometimes as random PCMs can sometimes go a little wonky and the tune can glitch. it that possible, and if so would a quick re flash solve it?
