That is the highest it read but the engine was still running, if for

May just be the engine being driven by the drivetrain.

Not likely since it was out of gear, hence "coasting". I am not even
sure the Chrysler has a rear pump in the transmission.
In 1986 I am not sure the EFI was all that smart anyway.

My cars coasting in neutral do not get 99 mpg these days.
