I was having some trouble with the SS. I was getting the feared Check Engine Light 3 times in a month. Never got around to scanning it, just reset via battery cable removal. I assumed it was the rear O2 sensor as I have a 3" catted down pipe and used the spark plug extender to move the sensor out away from pipe. Well.............. After driving through some nasty ass wet snow storm and slush, I got a "Service Traction Control" warning, flashing engine light, TC light, I had a light show on the dashboard!There was a roar or rough noise coming from engine/tire area??? Next day, the traction control light went away, but the car was running crappy, on 7 cylinders! I took it out and ran it hard and it finally ran better, for about a day and a half. Today, the Service Traction Control warning was back several times and engine was running like crap. Finally got a steady check engine light and read the code. PO301, Misfire faulty, cylinder1. Ok, I wait for engine to cool, go out after dinner and pull the wire and plug on #1 cylinder (glad it was the front side of engine). Well holly crap Batman!! Plug was super fouled because a piece of the ceramic insulator on the center electrode had broken off, probably some time ago. That plug couldn't fire a chain saw. I brought plug to Local Advance Auto and to my surprise, I got a new one for free. I guess Delco guarentees them for 3 years. Anyway, I replace the plug and she is running like a champ again, no codes, no Traction Control Warning. I am wondering if the misfire had anything to do with the traction control warning mesaage, or was it unrelated and I am going to see the warning again???
