I put the new wires on, car started and revved fine, i got in the car and it misfired as soon as i drove it. Stopped in front of my friend's house, popped the hood, and 2 wires (one on each side) had popped up. Put them both on (ouch, thanks shorty equals for being so hot!) and the car sounded just great/reved great. Drove it then all of a suden, misfired again. I got home, let the car sit for a few, then turned it on when i had to goto work, and the car is working great. I leave work, and the car is running great, get to a friend's house, sit around for a while and get back in the car....car is misfiring again (but all the wires are on). Now im on the road yesterday and in the lower speeds and rpms the car isnt misfiring. Get it up in speed and such and the car starts misfiring.

Did you check the plugs yet? You almost exactly explained my problem when I had a cracked plug. Ran fine sometimes and like crap at other times.

Suck it up, spend the $15 and 1 hour to change the plugs.
