Chevy dealer called today with good news and bad news. Bad news is it is my cats stopped up. Gonna have to replace them. Good news is they are still under warranty........

Thanks for the info. I am on the right cylinder. I am out of ideas. Took it to the Chevy dealer today. Keep this up and i will have to get a new one.

I swapped injectors with another cylinder. It didn't follow it. Dumb question, what is the firing order. Hope i am on the right cylinders......

Help!!! I am stumped. I have a bad misfire on my 03 SS. I had a friend connect his handheld to it and we drove. It only does it on high rpm. Misfire on cylinder 6. I replaced the plug and coil. Still does it. The only mods i have are high flow mufflers and PCM4less tune. Any ideas where to go next? If it was an injector, wouldn't it do it all the time? HELP!!!

WHEW!!!!!! So much information on this link........i think my brain melted.....
