RE: Running Rich
 

Flush oil, oil change (Castrol GTX is what i use), mix this thing call "Restore" in with oil, flush radiator, change antifreeze (prestone 50/50 is what i use) I did all that last week and so far i really notice a hugh/noticable increase in mpg. Im not sure what made my mpg improve but the Restore i use they claim that it restore ur engine and improve ur mpg.

smaller injectors?

RE: Running Rich
 

get some intake manifold cleaner.....its a spray can u let engine idle and spray into manifold and it burns up all the particles......then run injector cleaner with a tank of super unleaded gas......should be good.
