March Update
So we just replaced the cam sensor and the spark plugs. 3 of the plugs were a nice tan color as expected, however, 3 were boot polish black, obviously running rich on those 3 cylinders. Could be injector issues, but we're trying some injector cleaner through the gas tank first. Will run seafoam for the next few tanks and see what happens. However, the new plugs did make it better, so fingers crossed for the injector cleaner. Will update again in a few weeks. We'll also pull the plugs at the next oil change and have a look see.
