93' no spark adv & ping w/ load?
Hello Adv Tech-ers
93 Z28 Speed Density car
Bone stock!!!
TTS Datamaster (DA Rom) shows all timing is being pulled under load. You can hear audable pinging and the car agressivly bucks but only under heavy load (60+TPS)
Fuel pressure is at 42 at idle
Dealer installed with in 1000 miles;
New wires
New plugs
New opti
I changed the water temp sensor in the pump as it was
bad and causing the fans to not come on.
anyone have any ideas that I could add to my own?

Without posting some data, like actual advance and retard no's from the log, people are just taking WAG's.
