So I'm lighting up the message boards with some perplexing issues concerning a new to me 95 GT. One issue I have come across is a hesitation/stuttering/lethargy to the car. While checking out the ignition system components I observed that the cap/rotor seemed (not stock), but new. I replaced the plug wires, and was going to install basic autolite 25's when I noticed that they would not screw into the heads. Maybe it was my mishandling? Anyhow, the car currently has Champion RS14YC6 plugs. The Champion plugs have a much longer thread length than the Autolite 25's. I have 3 questions:
1. Could these be the wrong plugs?
2. Any clue why the Autolite 25's do not seem to screw into the heads?
3. What, if anything, am I missing?
