Hi there, I just got this truck and it's my first look under the hood.
Its a 1985 S10 4x4 Tahoe 2.8-carb that is 100% stock. (or rebuilt) calif. emissions label #UDW, vin #1GCDT14B4F8194102
The parts and location of controls via Chilton's manual is vague at best. Let alone trouble shooting so it be awesome if someone can confirm a couple things are correct (or not) for me.
It does have a ESC module. It does not have a knock sensor. (searched for a hour easy) The ESC is on the firewall near the distributor. (has a #P2002.8-1) The timing can fail to full advance with no error code. A ESC problem could cause 'spark knock' even at idle when the engine is cold.
Thank you Danny
