REVZ TO9

UPDATED again: The dealership called and said my car is back to normal now. That one cracked spark plug is what caused the compression leak and all cylinders to misfire. Kinda like a domino affect. So yes, if one is bad, then it can cause the others to misfire. They did a compression test again afterwards just to make sure. Must have been one hell of a faulty spark plug I guess. I only pay $300, instead of $1500-$2000 like I thought in the beginning. I got lucky on this one! I was gonna say how can this be so serious? I baby my car and it has only 59K miles!
