I have recently bought a 1992 Pickup and it has a 2.3 four in it. I took it to have the emissions test and it severely failed the emissions test! The guy told me he had set the idle high on the carb because the engine would die sometimes with the a/c on. The truck went a little over 3 times the legal limit in the test. Is this simply a catalytic converter issue? The truck runs fine and leaks some oil from what looks like the valve cover and oil pan which seem typical to me for its age. I can smell gas in the exhaust quite strong. I looked into reviews of this trucks' reviews before I bought it and thought I was getting a good little truck perfect my my 30 minute daily treck to work and am fearing big repurcussions that I've just purcheasd a dishonest mans ex-nightmare! Any suggestions would be greatly appreciated.
