Raiderfan717171 Posted February 5, 2022 Report Share Posted February 5, 2022 I've been getting a P0306 code and a P219b code....here's everything I've done and I'm at a point where I'm not sure where to go. I've replaced: 1. All spark plugs 2. All coils 3. Fuel injector for cylinder 6 4. Both oxygen sensors 5. The MAP sensor Nothing seems to work as the codes come back up after like a day of driving. Also the engine seems to "flutter or sputter" at about 45 mph up to 60 mph. Not dramatic but you can definitely tell. Quote Link to comment Share on other sites More sharing options...
John/Horace Posted February 6, 2022 Report Share Posted February 6, 2022 Compression in cylinder 6 would be useful information. Intake manifold gasket leaks can create cylinder misfire sometimes. How many miles on this engine? Quote Link to comment Share on other sites More sharing options...

John/Horace Posted February 9, 2022 Report Share Posted February 9, 2022 Fairly low milage. Was engine using oil when problem started.? I would check compression, leak down test as well. All wires under hood in good shape, no signs of chewed wire harness? Quote Link to comment Share on other sites More sharing options...
Raiderfan717171 Posted February 18, 2022 Author Report Share Posted February 18, 2022 Oil consumption is normal.... all wires seem in good shape...cant see any damage to them Quote Link to comment Share on other sites More sharing options...

John/Horace Posted March 7, 2022 Report Share Posted March 7, 2022 Which is good news, that’s a decent number. Might be two different problems or just one thing, hard to tell. You seem to have all cylinder 6 misfire causes covered except intake manifold seals, or maybe CPS sensor. They are a wear item and can sometimes cause misfire codes. Here is a list for p219b. You have a lot of that covered too. Still a few things. |P219B code possible causes Leaking or contaminated fuel injectors Low fuel pressure or running out of fuel Leaking evaporative emission (EVAP) canister purge valve Exhaust or intake air system leaks Exhaust gas recirculation (EGR) system Positive crankcase ventilation (PCV) system is leaking or the valve is stuck open Ignition system Incorrectly seated engine oil dipstick, tube or oil fill cap Raiderfan717171 1 Quote Link to comment Share on other sites More sharing options...

I'll check all those next. On 2/6/2022 at 7:22 AM, John/Horace said: Compression in cylinder 6 would be useful information. Intake manifold gasket leaks can create cylinder misfire sometimes.
