O2 Sensors '08 Viper
I have a Dodge '08 Viper with 4200 miles on it. I'm getting trouble codes with the engine light on for what appears to be the O2 sensor. Car will not run over 2500 RPM.
Trouble codes are:
P2273 rich, oxy sensor
P0304, cyl poor misfire
P0316 misfire at 1st 1000 rpm
Can anyone offer some advice on what to do to try to correct this. I can assume changing the O2 sensor or sensors? And I'm guessing there is only one set of O2 sensors, nothing "downstream" near the cat's.
In addition to add to it, it appears that the outer protective plastic casing that is use to protect the wires coming from the O2 sensor has gotten so hot, they melted although the wires and protective coating themselves look okay.
Note.....Hennesey Stage 1 performance system installed which includes headers, high flow cats, high flow air filter and tuning.
Thanks.
