Answer 1

P1351 Multiple misfire

This is a multiple misfire code condition with injector shut down for that particular cylinder, What this code should be named is "crankcase ventilation system causing the misfire" When this code is encountered, I use the oil dipstick as a troubleshooting guide. with the engine running pull up on the oil dipstick, , if there is a strong vacuum this would indicate that the PCV system is open. What the PCV system is commonly reffered to is the oil drain back its tubes tends to fail and the PCV  which leads to misfire condition and rough idle.
