I'm having a weird noise/roughness at idle, I've gone around the world with it, and come back to oil seperator/hoses.
This all started shortly 5k miles after the dealer did my valve ticking recall.
Since then I've change just about everything.
Intake/Exhaust Vanos Solenoids
Intake/Exhaust Camshaft Position Sensors
A Billion Bottles of Fuel Injector Cleaner from Redline, Chevron, Seafoam
Recently did the carbon cut out and cleaned the MAF.
Only thing left is my Oil Separator for the idle issue.
Gotta pay to play.
