I think the first part of your statement sums it up. But any chance you got bad fuel? Check all the usual stuff, ice pick injector harness & look for issues with wiring around alternator bracket. Run injector cleaner? Did this just start or has it been going on for a while?

Idk why LLY's are so bad for knock. Mine comes and goes as it wants. I believe most of my knock was actually coming from my hydroboost/power steering.

I'd run down the fuel system first. Check filter head, new filters, check harness etc

This time of year is common to hear this type of.complaint. most tuners don't adjust the timing compensation tables and the stock ones are horrendous in cold weather....can you say advanced timing!

Do you have a CTS to watch timing or fuel pressures during the problem?
