The car is now definitely fixed and a blast to drive. Sometimes, even tho' the engine is suffering a bona-fide misfire, no misfire codes are registered and no Check Engine Light (CEL) comes on. NOPE results remain the same. Here we have a P0301 cylinder misfire code on a Chevy 3. Bought the car 2 1/2 years ago with 50K so I doubt spark plugs were ever done. it read "cylinder misfire" i just bought this car at around 78k without any maintenance records so i am unsure where to start by fixing this. If the misfire is not specific to one cylinder, it’s likely because the engine is not getting enough air or fuel to run properly. Replaced the ignition coil on cylinder 3 and she runs like a champ again! Quick note: posters above are correct on the FIRING ORDER being 1-3-4-2. How much does it cost to fix a misfiring cylinder? My check engine light came on so a friend ran some diagnostics and found out that a cylinder is misfiring.
