Idle misfire
I have been dealing with a random misfire at idle bad enough engine light flashes.. but misfire goes away with a little bit of gas given to it..
codes are P0300 P0303 P0304
I have changed plugs, coils and both vvt solenoid
And checked compression have 160 across the board
2008 lnf
Would a bad hpfp cause this

I'm thinking of carbon crusted intake valves could be causing misfires. Just my 2 ˘. Intake valves might not be closing all the way. I've read old posts on here that this has happened
