whats flex fuel? is that that new thing that chevy is doing with the corn?

flex fuel is a something the automakers are doing so that some vehicles can run on the e85 ethanol or plain gas, you can tell usually by the VIN #, a flex fuel truck has a number 5 in the 8th spot on the VIN, a non flex fuel truck is a number 4, it has all to do with emissions and other bs that the government is making them comply with.

oh and there are 2 o2 sensors, one on the exhaust manifold under the hood, on the driver side, and one behind the catalytic converter on the passenger side under the truck, back by the door.

 

[domesticracer1]

which sensor would most likely be bad you think?

 

[Hucko]

prolly before the cat, considering the one after the cat is a different code, because mine has gone bad haha.

Also do a free carfax check and it tells you.

i know the one for the after cat sensor is a P0420, call the dealer ship or o'reillys or autozone they should be able to tell you for sure what that code is.
