My evo is running a low idle when I come to a stop died a couple times I had a code that comes and goes It was p0090 just started doing it. my battery was replaced doubt that had anything to do with it and I think it might be running lean at idle cuz of it mods are that came with the car when purchased full uncatted exhaust and greddy boost control and intake filter just need some help were to start looking

 

These are my plugs

 

I think the plugs are too "hot" if im not mistaken there needs to be 3 threads with carbon on em. I only see 1

 

Heat is best determined by looking where the color changes on the ground strap - in this case it looks Okay but the pic is pretty potato-y.

@OP, check for vacuum leaks, your mods shouldn't be causing lean idle unless you have some cams you didn't know about or something :P
