Hope someone can help me out here. My car just registered a code P0300 which my scan tool registered: "Random Multiple Cylinder Misfire Detected" The car had done this before about 2 months back then stopped doing it. What it did was like stutter when I start the car. Sometimes the problem would last a while then dissapear for a long time but it happened again today. And this is after the car had already been driven about 12 over miles so engine was still quite warm. Just went into Costco bought a few items and about half an hour tried starting my car and in idle mode it kinda stuttered or sputtered but the engine did not die out though it sure seemed like it was going to. Now before I take it to the mechanic I would like to know what you guys think. The car is a 96' V6 3.8LT Automatic. Last tune up was done around May of 2003 and I had the plugs and filters changed. Even had an Induction Service done. Can it be time for another Tune Up or what else could be the problem. I just don't want to get burned by the mechanic.
Thank you for any response. Winston
