Shaftsbury, Vermont (SW VT) | One more thing to check is the coolant temperature sensor. The one on my '94 went south, and the engine ran very rich and then fouled out the plugs. I think the guy said the oxygen sensor was reading lean, too. 'puter thought the engine was cold and made it rich like a choke would do. Also thought the engine was running lean, and richened up the mixture. Bad news all around. Had to get it towed home, and spent $$$ on a guy to hook up a scanner, and then buy parts.
