help reading my plugs....
These have been in for about 8K miles. last time i changed my plugs they were a little fouled but thats it. ive had starting issues recently so i pulled the plugs... ive never had such heavy flaky deposits, and irregular coloration. your thoughts please 
btw, the car is basically stock besides a DP & High flow cat. I also *may* have a very slight coolant seal leak. Injectors have not yet been cleaned. 90K stock motor.

ha, no one is any better at reading them than i am? i guess im not as bad of a wrench as i thought 
. anyway, i sand blasted them and the car runs rock solid now.... i just want to figure out what if anything is causing the problem.

what heat range are those? im not an expert at reading plugs either, but those dont look too pretty. im not sure if thats a carbon buildup or pitting caused from an overly lean condition. what are your driving habits? do you run it hard? alot of stop and go? or do you frequently start the car and shut it off without fully getting it warmed up? Im leaning towards a carbon buildup but again not an expert.

. little stop and go and it always gets warmed up to full operating temp before shutting down.
... and the last set that came out were not anything like this. i try to change them every 8-10K miles.

i just recently changed my plugs, they looked like that. i would say they looked even worse. I havent changed them since i got the car... so that was about 14k on them, plus however long they were in the car before i got it.
One of my plugs even had some wierd nasty sticky buildup going up the plug. strange.
