k i run the car it idles at start around 1100 rpms...which is fine...a/f are around 14:1 at idle in boost 11.5.1-12.5.1 which is also good. when ive been boosting a little and stop at a light the idle drops to around 500-600rpms...and sounds like it has a stall or is stalling...i just but new plugs in today...zrf7f11 and gapped at .28 im running rich but not as rich as i was...after a 30 minute drive i checked the plugs and they are totally black from core to strap...what the heck is going on any help appreciated.

I have this same problem accept my plugs are black but the strap is past the bend towards the ring, but my a/f ratios are still lean.

I am 2 steps colder.

do you have the idle problem also? and does it seem like the motor jerks or jolts around 10%throttle between 2000-35000 rpms if your just cruising...?
