I’ve recently replaced the engine in my 2007 Pacifica. The newer one has half the mileage, yet the mpg has reduced by about 25%! What gives? I figure it must have something to do with the computer but if I knew for sure, I wouldn’t be here asking your advice! Help is greatly appreciated.

New engine, LESS mpg? Huh?

Got it. Many thanks again.
