Hello, Im working on my 1999 2.5L 5spd Boxster. I am having some issues with the timing chain on bank 1 side. Codes are p1340, p1319, p1313-1315. All related to bank one misfires and timing. I pulled timing plugs today and verified timing marks were correct on cam in regards to crank. Using my foxwell scan tool i can look at camshaft deviation. Cam 1 shows 25....while cam 2 shows -6. i understand they shouldnt be more than 6 degrees apart from each other. This leads me to believe either the sensor on bank 1 is faulty, or the variocam solenoid is stuck in fully extended position. Can anyone shine some light on this for me? I can remove the cam cover again and pull the solenoid to inspect. Thank you.
