You don't see too many cases with #1 and #4 misfiring, since they are at opposite ends of the engine. the vairiable valve timing, (AVCS) shouldn't be the source of the misfire. The OCV (Oil contol valve, car has two, one for cylinders 1&3 and 2&4, is a likely cause of the misfires, if it's nothing else.) You are using at least 91 octane, right?
