Hey guys I need some help with my truck, it keeps giving me p0345/p0349, I’ve changed coils plugs both camshaft sensors and vct solonoids and it’s still giving me the codes... every time I rev it or try to drive it it bogs down or almost dies out. I have not changed the timing chain at all. The weird thing is when I clear the codes while running the engine automatically starts running better instantly? What do you guys think ?

 

Check these out. Check the 5 volt reference signal to the sensor.
