Super bad fuel milage!

[stclist000]

I replaced my fuel injectors a month ago, one was bad had plastic broken on end. Anyway, I was trying to inprove my fuel milage was getting about 12-14 mpg city, now getting 7.5 mpg. Tank does not leak, many new parts , plugd/wires, fuel filter, air filter, different throttle body, my other one had bad o ring seals on linkage. different maf, and other parts. I got the injectors from a junk yard, same engine and they looked newer. But they were shorter than my old ones , one of the newer ones just keep leaking at the seal went through 4 o rings and decided to put one of the older larger ones on and it did'nt leak. Runs fine, idles fine, but my milage is cut in half. Am I going to have to replace the injectors again?

go get all brand new injectors. the ones in that yard engine may be bad

you may have grabbed higher flow injectors.

Those are one part that I prefer to buy new, OEM, rather than after market or used.
