After changing plugs and wires on my 1997 Blazer I have misfiring...

Brings back memories - a buddy and I each took a bank of the V8 he had in his car to replace the plugs and wires when we were in high school. I replaced one at a time, he pulled them all and then realized the error of his ways. He figured he might have a particular pair reversed and, sure enough, the car ran rough afterward. We learned a second lesson that day when he tried to switch them while the engine was still running....

Chuckles change the cap and rotor. I can tell you that you need to sit on the engine to get to it and a mirror to see the back screw. The new cap comes with screws but try to save to old ones. You may lose one or two trying to thread the rear one. Trust me I know...LOL

Why did you change the plugs and wires in the first place, was it mis-firing then?
It's also possible to have a defective plug/wire in the new parts.

Up and running without misfire! Thanks to all you who responded! Special thanks
...to the tow guy on this one. My problem ended up being caused by a plug wire routing error. A friend of mine helped out with the job and I didn't notice until checking, but he ran the wire for #3 under the hoses and other conduit on the passenger side there. I don't know what it was on but you could see on the wire where it was getting hot. I re-routed the wire, let the engine warm up and no misfire. Looks like problem solved!
I might try the cap and rotor for an enhancement Mike. It could run a little smoother I think and maybe that'll do it.
Thanks again y'all!

Will do...I'm hoping that It'll hold up...the high temp silicone barely shows the mark from it, but obviously it was to hot. Thanks for the heads up.
