How do you diagnose a cylinder misfire?

The PCM can detect when a cylinder decelerates (an indication of a misfire), store a Diagnostic Trouble Code (DTC) in memory, and turn on the Check Engine Light. Some car computers detect misfires by measuring electrical activity [ionization] at the spark plug electrodes.

How much does it cost to fix a cylinder 2 misfire?

For basic head gasket job you’ll spend $2,100.00 with just cylinder head resurface. If the pressure test goes sideways and you need a valve job add another $800.00.

Can fuel injector cleaner fix a misfire?

Why is there a p0302 code on my cylinder 2?

It’s worth noting that, if other misfire codes accompany a P0302, there will likely be more than one potential cause. Code P0302 by itself is a good indicator that the problem is with cylinder 2 only. On the other hand, multiple misfire codes can indicate an issue, such as a vacuum leak or low fuel pressure, that affects various cylinders.
