- 2000 explorer xls sohc
I have a 2000 explorer 4.0 sohc its a recent purchase ..I found out that the motor was swapped for a sohc, it had an original ohv.I put a k&n airfilter on it and changed the oil twice... Since day 2 I have been getting what sounds to be lifter noise at a cold start ..buts disappearps after engine gets to operating temp.Nothing has fixed that this far.. now I also am getting p0171 and p0174 codes both banks lean.Could I have a dirty maf sensor..or clogged catalytic convertor? When I changed the plugs the porcelain was near melted and it always has a burning kind of heated exhausted smell? ?
The truck runs great no driving symptoms does seem to lack power.
I read that oiled air filters cause maf issues. And no I do not believe it is a vaccum. Or intake leak
