I exchanged with a guy a know 8.8mm wires for a set of lug nuts. I installed the wires but they were to long and the openings to small. Anyways i put them on and the drove drove the same. When i arrived at a stop sign a let go of the gax so the car could slow down and all of a sudden it reacted like a standard car does .When you drive a stick and it's in gear and you let go of the gaz it slows down all by itself that how my automatic did. The next day i took them out and instaled my NGK's but it was misfiring so i change the wire that goes from my coil to the distributor. What should i do install the 8.8mm or NGK's.
