occasional code 43
my 91 305 tpi is giving me all sorts of issues and eventually causes a code 43 rough idle and stalling at idle randomly , I've searched on google and this forum and can't seem to find a straight answer, can someone please help me figure out code 43. I've changed the spark plugs, air filter, ignition module, knock sensor, fuel filter and fpr...I used to get code 45 but it went away after replacing the cat...
