Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hi, After a waterpump replacement I am getting codes misfire codes during idle (haven't driven it yet): P1319 - P1316, Cylinder 4-6 misfire emission relevant Some various oxygen readings: Oxygen sensing 1-3: 0.95 Oxygen sensing 4-6: 0.75 Oxygen sensing 1-3: 0.85 Oxygen sensing 4-6: 1.20 I guess this is Lambda? So it should be 1 or at least they should be the same? When I removed the waterpump I removed the cats and all the sensors, could this simply be a bad sensor before the cat? Or what is that value? I also managed to pour plenty of coolant over the engine, but bank 4-6 is the right side right? It also takes a while for these codes to appear, it idles fine before the codes.

POST 2Original post

When I did my water pump recently I also had to remove my cats, but I left the sensors still plugged in. Could you have swapped the 4-6 pre-cat/post-cat sensor wires? The 4-6 cylinder head is on the passenger side. Also check your MAF connection.

POST 3Original post

My thoughts as well. I did and after swapping them to their correct position have had no issue for 500 miles.

POST 4Original post

Swap the coils from one bank to the other and see if the code follows them. If it doesn't then swap the plugs from one bank to the next and see the code follows them.

Bingo! Thanks!
