hey also new at this but but i might be of some help. from my exp. code 43 comes up when a/f ratio is screwy. this can happen all kinds of ways but the most common on our year tegs is a bad O2 sensor. unless you have fuel system mod than that's another ball game. the reason your car runs and smells funny is because it is going into "limp mode" this dumps a lot of fuel so things don't lean out. try a new or diff O2 sensor preferably from a buddy's car ,there not cheap, and see if it clears it up. also clear the ecu of codes by disconnecting the batt. for 10 sec,s hope this help's
