Running poorly/misfiring, code 33

[MO LS Noobie]

Can you elaborate on this a little? This is the first I have heard about this. However I have been out of the fuel injection/tuning loop for a few years. Plus I do not work on much anything other than my own stuff, so I do not have much exposure to common issues happening to similar vehicles.
I am a small engine mechanic for a living, so I do not get much exposure to working on cars/trucks.

Try this link, it explains it better than I can.

This is one of the posts if you have trouble opening it. "I have heard a lot lately about the pickup in the distributor being the cause. The pickup itself or the trigger wheel (for lack of a better term.) Check into that a little deeper if you have not. It can develop a crack or get loose on the distributor and cause these types of problems."

"also ran onto one that exhibited similar symptoms that ended up being a faulty coil that was leaking voltage out of the coil wire tower over to the primary wire connector. I saw a loss of signal from the module accompanied with a marked increase of system voltage due to HEI voltage leaking into the primary circuit."
