Misfire In Bank 1

[coleycoleman1906]

is this the spark plug, Which one is Bank 1??

Search. Bank 1 = rear bank (Odd bank)

It could be anything ignition, or fuel related.

Start by checking/replacing the sparkplugs. (Search for spark plug threads)

Then move on to checking the injector & the spakr plug wire (DO NOT use generic wires. NGK, or performance oriented wires ONLY)

After doing above, you may want to check compression on that bank when the engine is hot & again when its cold. A friend of mine had a misfire code & it ended up being a crack in the head between the valves.
