fuel trims/spark advance erratic
timing light shows jumping at 2000 rpm
0 deg timing in base holds steady

i have tried blazer forum and s10 forum and i getting nowhere.
i was trying to get someone to look at my logs but had no bites. so im here . idk how to load a log on to the forum .
anyone familiar with the 4.3s my computer and what would cause this knock retard issue?
the only thing i can find that differs from my brothers blazer logs is the knock retard his has a refurbed motor that runs great and passes smog
