Hi

Brief history vehicle came to me 2 month ago as a none starter check over various fault codes all relating to cam timing pop rockercover off checked timing and it was miles out fitted new chain and tensioner cleared engine run lovely job done
vehicle got towed back in the weekend same fault check out codes 2781, 2782, 27c1, 2731, 27bb, 27c3 checked timing it had moved reset timing started fine all codes gone took for test drive all ok monitered data when running inlet cam fluctuating 0 degrees to 29 degrees exhaust cam not moving after revving engine cut out wont start rechecked timing it had moved the same amount it as if the camshaft are retarding when revved high but not advancing when returned back to idle any ideas on this would be appriciated
