Here's the gig (ignition on / engine off) (Gm 3.6 over Advanced exhaust) When you plug in all four actuators Three of the actuators engage and when you start the engine it runs absolutely terrible. The fourth solenoid has power but does not activate the solenoid but the solenoid is good cuz I checked it manually. But with the fourth one plugged in and the other three solenoids unplugged the engine runs perfect cuz three of them are not engaged. plug any other actuator in and the engine runs pathetic. Any info much appreciated
Just changed the chains and guides and tensioners on my 3.6 and it still has the same valve trane rattle and p0016 and p0017 code? Could it be the vvt solenoids?
