b20vtec missfire

[DA9 TANK]

on my b20z2vtec my motor has a missfire in cylender 2, wut are all the things to check for to fix it, i got new dizzy, wires, plugs its geting fuel to all injectors, an i have 175 compression all across...

any ideas on wut it can be

I don't know if you know what your doing but you have to have these required things to ignite:
Spark
Compression
Fuel

You said you've got all 3 of those. Go through all of them again I would personally do this:

Take a spark tester to the wire to plug to see if there is spark to the cylinder, if you don't have it take the sparkplug out and hook it to the wire and look for spark.

Take a Diode tester to the fuel injecter to really make sure its getting a fuel jump.

If your really noob which I assume not, but check you're gaps on the spark plugs.

willing to bet you need to gap the plugs to the correct setting your slightly misfiring cyl 2 also make sure tat the diz wire is sealed and snapped correctly meaning its not losely attached to the spark plug

I'm assuming he fixed it.

check mark to all three... an also after i turn my car off after its been runing for a little bit i think there is still sum gas in that cylinder, as like it never burnd all of it.

you think if i just bout a nother head i wont have that problem... and also im using a LS fuel rail an injectors. may that be a problem?

Sounds almost like not enough spark to ignite the fuel during combustion. Which would mean gas left over in the combustion chamber.

 

[DA9 TANK]

so how could i fix that problem?

 

[XxCaryxX]

Re-check all things that effect spark would be a place to start. Past that is when you get out of my area of knowledge.

 

[DA9 TANK]

lol, k

 

[blaketeg]

sounds like a bad plug wire or fouled out spark plug

 

[DA9 TANK]

any kinda way to check it, if i take out tha spark plug an plug it into the spark plug wire an crank it over i will see a lil cunt hair spark. but now that i think of it i should do it to the other ones an see if they spark bigger or the same.
