Friend’s vehicle. OBD-II codes indicate Intake Valve Timing Control Bank1 and Bank2. Vehicle drives OK most of the time, but then has lapses of lost power where you step on the gas and the vehicle doesn’t accelerate accordingly. RPMs rise, but tranny doesn’t seem to shift at the right time. Overdrive button OFF doesn’t seem to have any affect. Codes have been erased and returned the next day.

Is this Camshaft-related, as in Camshaft Position sensor? I had this issue with my '97 Taurus, but in that case it threw the code explicitly for the CMP sensor.

Believe it or not, an oil change solved this problem. He was low on oil.
