I'm getting a check engine light on bank one intake cam position sensor fault(incorrect position to crank position) only after I keep rpm up with foot on throttle. At idle its fine, but once I hit the throttle and let go the rpm drops to 0. It also has two pending cam position codes on both exhaust cams(slow to recover). I r/r intake bank one cam sensor and also the solenoid to the vvt. Any clues to what is going on would be much help.
