Code P0171 after changing upper radiator hose
It's only code P0171. No P0174 to go along. I have checked all of the intake and it looks fine. I does seem like the wiring for a 02 sensir just below the hose was in the way of getting the hose in and out.
Where do I look? Did I mess up an 02 sensor wiring?
Thanks

The reason I am concerned in because it seems like both of those front sensors by the hose got really abused while trying to install that hose. I replaced the IMT o rings and all the intake manifold gaskets over a year ago, so that's not likely te reason for the code.

The code is indeed saying that the fault is with the firewall side sensors. It has to be your call as to whether to go with the code or your gut feeling for the other side!!
Don't know about the US but in UK the Dealer's price for the OEM item is about the same as a reasonable quality aftermarket one plus it's guaranteed to be the right one.

o2 sensors
Spike,
I bought mine off eBay. I paid just about 60 bucks each and were OEM. Plug and go. No splicing. Just make sure you get 2 gray plugs and 2 black ones. I did all of mine so there is no issues about that. The ones up front were easy as long as you have the crow foot remover.( got mine from auto zone for 15. Bucks) the back I took off the intake to make it a lot easier.
Good Luck,
The Dr!

I m a little confused...do you think that it's possible the front sensors are responsible for that code?

Any brand or part numbers? I see NGK, Bosch and Denso available.....

Air intake leak between MAF Sensor and throttle
Fuel filter / system restriction
Fuel injector restriction
Fuel pressure sensor failure (low fuel pressure)
Low fuel pump output
HO2 Sensor(s) harness wiring condition fault
Exhaust leak (before catalyst)
ECM receiving incorrect signal from one or more of the following components:
ECT Sensor, MAF Sensor, IAT Sensor, IP Sensor, EFT Sensor, TP Sensor
Some of those possibilities seem less likely, noting that the code is for one bank only, but it's an uncertain game!!
