2000 Civic EX, 84K miles, 5 speed manual.
While slowly accelerating from a full stop, my car seemed to hesitate for a couple of seconds. It then paused and I heard and felt a sharp "knock" in the engine, I also noticed a vibration hitting the hood from the inside each time one of the pistons fired. The engine didn't shut down as if the timing belt had failed, though. I was able to slowly pull out of traffic and, after rasing the hood, found that one of the sparkplugs on the row closest to the front of the car, was raised up completely out of the head; sparkplug wire intact. The sparkplug threads did not shwo any signs of having been stripped before coming out of the head, but around the plug just below the ceramic is a hard, black plastic sleeve. When I slowly pulled out of the traffic, I felt and heard a hard knock each time that piston came up to meet the plug. I didn't have to travel more than a few feet to get out of traffic, and thena t that time I turned off the engine and have not retarted it.
Any assistance is greatly appreciated.
have the same problem?
