Hello everyone, Im hoping someone may have some insight into what is going on with my C30. I have a 2009 T5 RDesign that has a hesitation under load that starts at around 30 mph and clears up around 40 mph then will reappear around 60 mph or any time you accelerate. I scanned for faults and and got 6 codes P0305-Cylinder 5 misfire and 5 codes for P0351-P0355 which is Ignition coil A-E Primary/Secondary Circuit. Is it possible all the coil packs could fail at once? I find this very unlikely especially since they were changed a couple months ago. I know the coil packs are not Bosch packs, but still would find it unlikely that all the packs would fail at once, so I'm thinking is there something wrong with the ECM or wiring? Coil Packs grounding out? I still have the original coil packs and they were good so I plan on changing one to see if the code for that cylinder goes away, but I'm not sure it will. Any insight or suggestions? Thanks everyone in advance.

Could be camshaft positioning sensors or solenoids.
