new to dodge,just bought my truck a few months ago,ran like a champ.recently have lost alot of power and milage.did a tune up and nothing changed.only code found is an evap leak,did not believe this to be part of the problem,gonna smoke test the vacuum system anyways.would love to change fuel filter but not into payin 200 for a new pump,very bad design idea.any ideas how to eliminate the onboard filter and install an inline filter with check valve to help with bleed down??

 

o2, cat evap i would check it out, did the code come on than you had the problem? Sounds like fuel or spark or too much back pressure.

 

Might want to check out the egr valve also.
