2000 Honda Accord LX 4 Cyl 2.3L
Identifying a #3 Cylinder misfire.
Typically with a high mileage car that has a misfire, i do a compression check for that cylinder and compare it against the rest / and factory standard. If cylinder three is not developing enough compression, then you will have a miss fire. Essentially, an engine is a glorified compression machine. No compression, no power. No power, will equate a miss-fire.
