I am appealing the G2 gods! I am going crazy trying to figure out why mycar keeps putting out Code 43. I replaced two new O2 Sensors and it still does it…i am stumped please help! I have adjusted my fuel pressure to run rich, lean, stoich and it sets the code at threee fuel pressure levels? Timing advanced to 18 BTDC and it has been like that for the last 6 years. Not sure what else it could be…the defination of the Code is Fuel System Supply\ Shorted O2 Sensor Circuit. PLEASE HELP!
dude i just got a 43 the other day, reset the ecu and its ok now.
before that, i swapped heads and got o2 sensor. tested it with a voltmeter and checked out fine. eventually replaced the distributor and it went away. wierd.
at first i thot the o2 was out cuz i sprayed the manifold out with degreaser and didnt remove the sensor…
