Maybe you didn't plug the coil in all the way.
Good luck!

I never claimed to be a "boost expert"..... Until now everything is here-say....
Seriously, I want to pull the plugs once and set their gaps. If .030 is the accepted norm that's what I'll use. I'm simply asking for some empirical evidence to support it.

Beyond that, I remember years ago some Buick guys running crazy small gaps and making more power that way, just due to maximized spark energy. I'll see if I can dig up any info on that. Edit: Buick expert informed me that some were running down to .022" gap at 30 ish psi boost on the stock ignition.

HELP!!!
So i replaced the plugs with the autolites and managed to crack 5 out of the 6 insulators (obvious misfires) but i replaced them with new units was even more careful replacing them and it still pulled up P0300, P0304, and P0306 (more misfires) so i pulled them out and this time no cracks but still misfired like crazy. I replaced all those with the stock plugs(none are cracked) and it is still misfiring like mad with the same P0300, P0304, and P0306. Any suggestions here? I'm ****ing pissed i have a 50k dollar truck that wont run. it has 14k miles on it. Any suggestions on what to do? i'll have it at the dealer tomorrow but would like to avoid that if possible.

You sure you are getting all the connectors back on? I mean the ones for the coils and any others you might have pulled to get the plugs out.
What are you changing them with to crack them? Don't have a plug socket with the rubber grommet in it?
