@gtrboyy knows how to on a VN. You should just need a jumper wire. VR like I have is slightly different as I have OBD port. But still use paper clip or ALDL software and a laptop.

Yeah I'd say so. They will probably need a Snapon scan tool though.

Use a paper clip bent in a U shape or use a piece of wire and bridge A&B together, plug is located under the glovebox near the kick panel.

You don't need to visit a mechanic to check for fault codes. As Comcal says above just use a bent paperclip to bridge the A & B connections on the diagnostic plug. With the ignition on the engine light will flash like a kind of morse code to give you numbers to point you to faults. If you use the search function on this site you should find a more detailed set of instructions. I just had a look but so many posts came up and I don't have time to trawl through them.
Get back to us and ask more questions if you are following up on this and you'll get more help.

Speaking from experience it sounds like the O2 sensor but of course it could be anything.
If the car has ben sitting for long periods i would replace the O2 sensor anyway,cheap and easy to get at.
Good luck.
