Hey guys, just got done putting on an oil separator on my car and for some reason it started misfiring really badly... it just happened to be one of them things that happened the same time I was doing something. I pulled all my plugs and changed my wires. The plugs are only 3 weeks old and i'm running Autolite 25 platinums. The car was running like a champ for a few weeks and then in the last week seemed to run like crap. All 4 plugs on the pass. side were running normal wear. However, all 4 plugs on my driver's side are all white looking... It's hard to get a good picture but this is the best I could do (1 plug in comparison with the other side)

After I changed everything the car isn't misfiring anymore and it runs great. I'm running maybee a **** hair or 2 over 10degrees timing so it couldn't be too advanced. And even if it were all the plugs would be white wouldn't they? Not just one side. The book says the white means it's running hot. The next thing i'm trying to figure out is, how could only one side of the engine be running hot. I'm thinking maybee the o2 sensor on that side is going bad? And it's sending a different mixture to that side???? Any ideas?
