Getting unusually very poor gas mileage, No codes set yet, scanner shows a pending PO301 misfire on cylinder 1. After changing intake manifold gaskets, engine runs very well, better than it has in a long time, does not appear to be missing, checked gas lines, appears there are no leaks. I do have a p1870 code, Transmission component slipping, have not noticed any noticeable problems with the transmission yet. Thoughts?
