Read evidence and context

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.

Discussions that suspect a cause: 1

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.

Suspected cause
probably a coil on #1 cylinder.

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

I have the checking engine light on because of one of the oxigen sensor but now the cilinder 1 misfire code came up. Any ideas? thank you guys

POST 2Original post

Model and year please and what are the exact diagnostic error codes?

POST 3Original post

probably a coil on #1 cylinder. What mileage? Maybe needs new coils, plugs and 4 O2 sensors if they are the originals. I just did mine at almost 90000 miles. Amazing the difference that made to the running of the car.

POST 4Original post

#1 coil is prone to getting damaged by coolant draining on to it from coolant expansion tank drain hose... Check for overfill or drainage hose routing...
