Ok guys need some input. Last week I purchased an 1986 Grand National. 31000 miles unmolested down to the original paint and interior. The boost gauge in the dash cluster did not work when I bought it. I drove it home aprox 3 hours. About an hour into the trip, when going uphill, the gauge started to work when the turbo kicked in
, but just lit up yellow. It worked all the way home. since I've gotten it home last thursday, it doesn't work again. I haven't done anything to the car yet, as its going for a tune up tomorrow. Any Ideas where to start, without tearing the dash out?
