How do these plugs look?

I installed some new plugs yesterday hoping it might cure my sputtering problem...nope. These are in order 1-6 left to right. They had that light grey primer look and I was wondering if this is normal. I checked to rotor cap and dizzy also to cure the sputtering but no luck. I'm thinking my injectors are the cause of my sputtering and rich woes. Should I go with reman injectors to see if that clears it up? I'm also thinking the reason my CCP isn't cycling on is BECAUSE of the rich condition and the ecm sees to much fuel and not turning on the CCP solenoid because the mixture is too rich.

Re: How do these plugs look?

Plugs look good, even for the continued coding. Which means you have other problems, because they aren't black, which WOULD mean you're running rich.

Like I told you before, you have a fault in the canister purge system. The solenoid is supposed to be ON most of the time, and OFF when purging is desired by the ECM. Turning the solenoid ON stops the canister from purging, not the other way around.
