Default Is this plug fouled?

Still trying to figure out why my car will stumble at low rpms and wont roast the tires in first gear, so while i was doing the plug wires i pulled out one of the plugs and it looks like this.

Is this fouled? There is a greyish buildup on the top and the base of the plug is all black. i have also heard bad things about Bosch plugs in lt1s. could this be the problem? Thanks guys

That plug is very black. The plug is fouled many reasons for it to stumble off idle, vaccuum leak, exhaust leak, o2's, plugs, plug wires, coil, cap, rotor, tune, etc, etc

I was given a set of those plugs and I thought they were WAY to expensive.

The ONLY plugs I use are TR55 or autolite 106 and that is from NA to 15 psi boost...Who tuned your car btw?

Check all that I mentioned. Get datamaster is the best investment. It requires a cable then you can collect 20 files.

Try it you will easilly find this problem with it.

Well the plug DOES look black, but on the flip side that's a crappy pic :\ Use "macro" (flower pic sometimes) mode on your camera.

Right now, I'd say a little rich.
