1995 Ford Taurus SHO mileage: 93,000. I changed my plugs and wires the other day and found that an old wire boot had decayed and broken apart in my plug well. I fished most of it out but a good-sized piece (1/2") fell into the cylinder. With the new plugs and wires, I started it up to find a "popping" from the engine and exhaust. I checked and re-gapped the plugs and the idle was fine. As soon as I put it into gear the "popping" returned. When I open up the throttle, I don't hear it but it returns at stoplights. There is a slight loss in power off the blocks. Is it that stupid rubber boot piece or some misfire that I can't spot? If my wires were crossed from ignition box to plug, would that be a cause also?

The piece of broken spark plug boot that fell into the cylinder may have been caught under an exhaust or intake valve. This would account for the popping sound you are hearing. There is a chance that some crossed spark plug wires would also cause this problem.
