Re: Code 43
OK, going to suggest a few things:
1 - Could be fuel pressure. Get a fuel pressure gauge, hook it up, tape it to windshield and drive to see if it's dropping at all.
2 - Could be an oil leak leaking oil into the 02 sensor. Check to see if there is oil in the connector at this point if you already cleaned up the wires.
3 - coul be a loose connection. Chase the o2 sensor wire all the way back and unplug and replug the connections. Also clean if there is any oil.
4 - Could be some Bad luck with o2 sensor, check with multimeter, I believe it should show resistance between 10-40ohms. Anything outside will mean swap it with another and check again.
