Hello y’all,I have a 2020 stage 2 with Cobb tuner running sport tune 91. Have ams intercooler down pipe's, awe full exhaust that I’ve been running for a year. Recently during deceleration I heard what sounded like a knock or rattle come from engine bay only lasted a few seconds. Nothing performance happened and no CEL. Few hours later same thing more noticeable and loss of power and threw the above mentioned two codes. Used my Cobb tuner cleared the codes and drove it home. Checked engine oil level from what i had read here from members and was spot on. Removed tune and went to stock same problem. Changed cam position sensor bank 1 sensor b and problem was still present. Changed remaining 3 sensor and problem was there only one time. Took it to dealer and they have had it for three days and said they can’t replicate. Anyone heard of or have this issue before? Lastly only threw CEL and code once. Thanks in advance for any advice
