truck has a little miss, think its the wires

I just replaced the spark plug wires today in a 1996 Chevy. After saying some choice words about engineers placing the distributor coil at the rear of the engine. I decided to look at it from different angles as mentioned above with removing the wheel and then trying from above between the engine and firewall. I couldn't jack the car up high enough to get underneath. So I drove the car up on ramps and had ample room to manuever under the vehicle. If you enter from the front of the vehicle on your back and slide towards the rear, you will see a hole and through there you will have a direct shot at the distributor. My wife helped me by feeding wires ONE AT A TIME as I unplugged the wire from the distributor coil and let her pull it up and then would feed me a wire and I would plug it in and then so on with the other three. This process took about 20 minutes after, of course, finding the proper way to get at the distributor. Make sure to have a light shining down the space between the firewall and the engine so you can see what you are doing. Make sure to mark the wires before on the old wires and after on the new wires. You do not want to change your firing order! If you do some how unplug two and don't have them marked. The order is easy. Looking at the engine from the front of the vehicle - 1 2 3 4. When you are underneath the vehicle, the numbers are on the distributor. Hope this helps, it saved me about $200 by not going to a mechanic. Not too bad for a couple of hours of getting dirty.
