I have only seen fault code 53 so far. OBD code says it is overvoltage to TPS but data from logger show 0 volts or .5 most of the time.
I’ve slowly been working to shield all wires. Also will be replacing the coil as it is one of the few “old items” reused.
MSD unit is on the dash side of the firewall.
Next is shielded wires from coil to MSD. I’ll let you know.
Thanks for the reply.
