Suspect fuel injectors because running very rich. Code 0171 says 02 sensor and changed them with no luck.200000 miles on 2000 dakota w/4.7 don`t think its the mas air sensor. only getting 120 miles to the tank and black smoke with hard acceleration code also says running lean left bank...any ideas surely appreciated

I have a set of fuel injectors from a 01 I would sell for $50. Engine ran and had 120k on it.

I don't know if it your problem though but it could be.

I am in NW Indiana (near Chicago)

Tom, by chance are you losing any power steering fluid? If so that is the root of you problem. The 4.7's are know for having a leaking power steering pressure switch which pushes fluid down the wiring harness to the upstream O2 sensor and fouls up the connectors. Check it out.

Appreciate the offer but I think I read that they changed in 2001 to a 4 hole series. Curios to see what everyones opinion is on diagnostics

Daddio.....thanks for the heads up. Reservoir is at add. Code says down stream 02 sensor and left bank lean . Will check pressure switch. Down here on the Texas coast and dealership is very limited and long wait for service appointment.....Tom

Hi Guys,

Good post. I'm just troubleshooting and new to the 4.7 family. Is
the same 4.7 in the Ram that is in the Dakota? My Ram has a
random misfire code but doesn't seem to be running that rough (or
so I feel)

Does anyone know where I can find a good diagram online on the
engine components so I can follow along with the post and see
what you's are describing? Thanks!

Yes they are the same engine. Tom's problem ended up being the fuel injectors after all (I sent him the ones i had).
