My first thought is the ECM.
Pull the battery and let it reset. see if it makes a difference.
This car is 21 years old with high mileage and in need of some other repairs.
Now I have to figure out whether to repair or replace it.
ack. that is too bad.
I had similar once, a reset took care of it. On my jeep, also showed transmission issues, but the ECM was the problem gain, but had to be reprogrammed. ( known bug )
I ever mention i dont think computers belong in cars? :)
Must be an automatic transmission. If the car is that old I'd sell it.
Ahem, that might prove challenging to other than a salvage yard. Don't @ me.
So it predates the overwhelming computerization of modern cars.
