Broken fully always better than intermittent! I've chased intermittent faults for months before finally replacing something.

Recently chasing faults on wife's car for over a month, misfires random cylinders, replaced plugs and coils it gets better then much worse and says error with intake air pressure.

Problem is with Valvetronic. No excuse the ECU didn't flag properly. The requested and actual angle not close but the errors were everything under the sun besides the actual problem.
