Hi Bernie,

I'd suggest that you take the connector apart for the Throttle control switch.
get some 90% isopropyl alcohol and a tooth brush and scrub both male and female
connectors until they're shiny squeaky clean. Then blow out with compressed air. Then apply a very small amount of dielectric silicone or maybe CRC spray silicone that you can pick up at Walmart, then reassemble.

Service your ground wires, especially the two signal grounds for the ECU's on the intake manifold. Clean them, grease with never seez, and reassemble.

Reset the codes and see what happens.

Post back with your results.

Bill
