Don't put E85 in cars not designed to run it
Got a 2014 Hyundai Elantra setting a P2191 fuel system too lean under load. Smoke tested the intake and exhaust systems with no issues. Capped off the hose from the PCV to the intake manifold with no change. Fuel pressure in spec at 53 psi at idle and under load. Noticed the fuel smell was pretty weak and appeared very clear like E85. Used a water bottle for the volatility test and it is in fact E85 lol.
