Need some help and ideas. I took my car to the track tonight. On my very first run, I take off and about 3/4 the way down the track in between shifts, I lose power, and miss a gear at about the same time. The car ran, but didn't sound the same and had about 10% power. Took it to the pit area and started looking at it. One of the plug wires had popped off. We put that back on and started the motor. I had power again, but it sounded different still. A lot more rough sounding...remember, I have not exhaus, just open header. Sounded kinda like it was missing a piston or something maybe. Anyway, I ran a 15.735 at 67.97 mph that run. I did run again and got a 14.565 @ 97.05 and it felt like it had ok power, but when we were playing with it, if you unplug the 1 or 4 spark plug, the motor would die. If I unplug the middle two, it hardly makes a change. Any thoughts?
