rich fuel as you probably know could be lots of things, the diagnostics are not very advanced on these so dont show much.
could be high fuel pressure, bad injectors(15-17ohms bosch 13.5-15.5 seimems)dirty injectors ,dirty air filter, blocked cat, engine temp sensor(blue two pin,common problem),timing,bad dist. cap, rotor arm, leads, leaking exhaust, bad ecu relay(number 30 under dash relay board). lots of stuff. my 80 is also running badly on tick over but i am stuck. thinking of changing rocker cover gasket, manifold intake gasket, and lambda. as everything is getting old its become a money pit. dont think the engine sensor has anything to do with your poblem, but not an expert. so anymore advice from anyone might help.
