New to the site, lots of good info on here BTW! I have a 2003 2.0 DOHC ZTW
Has the P2195/ P0171 DTC
replaced fuel filter (no change)
cleaned MAF
changed front 02 (not bosch)
ran live data everything is in tolerance, running out of ideas. EGR gasket? I did the propane trick and starter fluid, no change. PCV hose is good (has the heat shield) new PCV valve. car has 127k just need my 28 avg mpg back!

Any help is appreciated!
