I am getting a P1316 (misfire causing excessive emmisions) and a P0304. The battery is good and I'm getting spark. New coil packs. I'm running champion copper spark plugs and 8mm kingsbourne wires. Compression checks out ok. New fuel injectors, fuel filter, and fuel pump. I have tried +4 spark plugs then went back to champions. I run 91 octane. I'm hearing ticking and gets faster when accelerating. Any ideas???
