My service engine light came on and I took it to an independent shop who informed me that I needed to replace my egr valve gasket and my upper intake gaskets. I replaced the egr gasket and the upper and lower intake gaskets figured I would do the lower since I am changing the upper. I did not have a scanner so I disconnected the battery while changing all the gaskets. I drove the Montero for 2 days and the check engine light came back on and took it to o'reilly and got it scan and the same code came up P071 and p0174 (bank 1 to lean and bank 2 to lean) I just don't know what else to do to the monty to get rid of that dreaded light.
your help would be much appreciated.
have the same problem?
