2011 Calais wagon with a 2013+ LFX engine in it
Drives so beautifully
But...get on the freeway and start going up inclines then grrrrrrr it starts starving for fuel or something. I guess it's a misfire...it just starts to run poorly and yep only when it's goes up hills. Go back to horizontal and it stops
So I've changed sparks plugs, coils, injectors, cleaned maf, put injector cleaner in it, put liquid molly through it, new air filter, running 98
It's still happening
What would U try next?
I'm thinking cam actuator solenoids?
Is there anyway to get to the heart of the issue? My scan tool has live data but where do U start
Or is there a way to test plugs? Such as injector plugs? Or coil plugs?
Is there a way to know if it's a misfire on all cylinders or just one?
