For last few weeks i have been driving my 1991 X with it transplanted motor from a 1993 ranger back fitted to my 91 everything has been fine but in the last week it has started popping a intermittant CEL on the dash.
Like i said the motor running fine except for maybe a little surging at part throttle especailly when it cold.
So today i ran my code scanner on it and both KOEO and KOER test both came back with code 41 my scanner reads "exhaust gas oxygen switching not present- always indicating lean"
now is this the O2 sensor that is being refered too? this motor did have an EGR on it but my 1991 did not so i trashed it and everthing related to it
and reused my 1991 intake manifold and exhaust header with the EGR port plugged.
can anybody confirm this before i run out and buy an new O2 sensor?
which is what i believe the problem is.
