Like Rick said, if everything else has been replaced - the most difficult happens to be what is left.

I'd like to smack the person that created CARB and some of the inspections with a 800 lb FROZEN tuna.

Back in the 1950s the car industry funded shill pieces to tell Us that smog in LA didn't come from cars.

I had this issue in my '96 850 a few years back. I replaced the PNP switch which improved things, but what really solved it was finding the melted wire short in the harness going away from the PNP switch to the ECM. Found it by looking for shorts to ground on the harness. I'll separated wires and reinsulated them, whamo problem went totally away.

I think I found the issue... upon replacing the PNP switch, I noticed that a pin on the connector was pushed in.

10 drives and no issues so far!

Wow, well done! Hopefully you have finally found the problem. That is very well found and it has taken a good eye to find it.

Let us know if it all stays good.
