After a 4th gear pull on the interstate a few days ago my GENIII Paxton Coupe started a misfire. After the interstate pull I limped a few miles home. When I popped the hood, the front plug wire on the passenger side was off. No check engine lights came on at all. I put the plug wire back on and the car still had the misfire. I pulled the plug and it looked fine and is still putting out plenty of spark.
Of my guages, the air/fuel gauge is reading a perfect mix, but the fuel pressure gauge is reading in the green also, but its a digital gauge and every now and then will just have the 3 dashes instead of a number. ---
Once the misfire started the smell of exhaust became much stronger and the car started to backfire on the passenger side some on my way home.
Any idea's?

Are you sure the plug wire is still fine? How do all your plugs/plug wires look? The stronger exhaust smell is probably a result from a cylinder not firing (no spark). Your A/F gauge may read fine because it may be located on the opposite side of the engine. Can you data log? Looking at what the O2 sensors are reading may help.

I haven't checked the wire itself, although they all look good on the outside. I checked the plug out of the car and the spark was great. I need to check the wire. As for doing the data log... I don't have the equipment or experience to do that.
