Umm, its not a constant miss, so the pulling the plug wire method is not an option, its a random miss. I did not think about a cloged injector, I have not replaced the fuel filter since I got the car, (about one year ago), how much is a new fuel filter?

Also, the oil is new, and the car does not smoke at all.

I also have a flowmaster muffler on it, if that can make a difference?
How can lower resistance plug wires, and a higher output coil be the problem? If anything I would think that it would increase performance, not cause lower perfomance... I am beguining to think it might be a injector, how do I know for sure? Is there a way I can clean the injector if it is cloged? I know I have taken one apart befor (not on this car) but, I know that there is a small screen inside of them that catches particals that are not traped by the fuel filter. Can this be cleaned?
