Hey guys

I pulled these stock platinum plugs on my car and replaced them with NGK iridium (one step colder) plugs. What do you think. Was I runnig rich (that's possible b/c I was running the pre-production ecu for 3-4 weeks while my ECU was in Japan). These plugs ultimately began misfiring - roughening up the idle tremendously. THe new plugs solved that problem in a snap.

Sorry, i didn't take a close up of the electrode itself.

THanks in advance

gurgen, I need a HIGH, HIGH res pic or a closeup of just the tip to tell you anything. From what I see it looks fairly normal, maybe a little blacker (due to rich fuel, perhaps), but not much more than normal.

If you cannot post one somewhere, email me at seannolden@frontiernet.net
