Local then that is really cool. If you run into problems you are not that far away. I still think you either have a vacuum leak or a stuck egr if these old cars sit they do all sorts of weird things. How does the motor sound in general motor quiet etc no lifter ticking does the motor sound like it is missing? You might want to look at the plugs if it has a vacuum leak the plugs will start turning white. Black means it is running rich etc
