computer reading p0171 error
I have changed the gas and air filter and the oxygen sensor and engine light still comes on.
When I changed the oxygen sensor, I noticed a crack in the manifold cover. Can this be the real cause of my problem? If now ANY SUGGESTIONS PLEASE HELP!!

Replacement of the 02 sensor is a very common misdiagnosis of the 171 and 174 codes.
You might also have an issue with the MAF sensor, which can sometimes be successfully cleaned. Visit YouTube for a "How-To". Be sure to use the proper solvent ! !
