Don't say plugs and wires!!!

I just changed them less than 10K miles ago but now I'm getting sporadic misfires. No SES light tripped but the misfires are there. WTF? I've had two of the three coil packs replaced not too long ago as well. I'm running Bosch Copper Electrode plugs, 93 octane, and the OEM wires. I noticed the problem first started when I put fuel injector cleaner in. Then the problem left and now it's back again. WTF?

Curious as to why you are running 93 octane?

Have you checked your plug wires since you've had this misfire? A plug wire maybe sitting on a manifold or something and burned through the rubber, then you may get some arching.

because when I put the fuel injector cleaner in, the car misfired like nuts, I put in 93 and it stopped misfiring...

wire, injector cleaner is a coincidence

93 stopped or improved the misfire you had? That doesn't make sense.

Are the misfires bad, like when you drive you're getting jerked around like a $2 hooker, or is it more when you open the throttle up, you feel a little bump here and there?

okay, i won't say it.

but i will say, do a search.
this is a basic and easy fix that comes up a LOT.
you may not have had enough fuel in the tank.
it may have just been really hot outside.
probably a bad wire or a wire grounding out in the wrong place. [img]graemlins/toto.gif[/img]
