I bought all of the needed parts including GM cam. we set up a 2014 engine that had 3000 miles on it as directed by the GM bulletin. After install the engine ran GREAT for the first 30 seconds. Then it started to jug, check engine light, setting a P0014. We tore it back down and double checked that the lobes on the new cam were pointing in exactly the same configuration as the one in the old engine (in case the GM counter had sold me the wrong cam). We swapped actuators. No luck. We double checked timing marks and they are exact. At this point I ordered another new pair of phaser sprockets and we are going to try that. Any ideas on what else we are doing wrong would be appreciated! Thanks</p></blockquote><p></p>
