It could possibly be tps, egr, map sensor, list is limitless on what it could be. Your s10 should know what it could be by using the pins below the dash

Oh, really? Great news, thanks!

Was hoping someone could tell me which two pins to jumper, and if any error codes stored, post them here and ask someone to look them up, LOL.
I found this list of ODBI codes for "4.3L VIN Z and W" - the 8th digit in my VIN is "Z", so I guess this is the right list for me:
