Default Ls block b16a head misfire

Ive had this car for a few weeks now running good then died on me I corrected the problem and now I'm getting misfires in cylinder 2&4. Anyone have any idea why? There's spark coming from the dizzy but not igniting the spark plugs. They spark plugs are fowling out pretty fast and turning charcoal black. Car is also running pretty rich but I'm sure it's cuz the fuel in the two misfiring cylinders aren't burning. Any help will be greatly appreciated.

Well we know we need 3 things spark fuel/ air (in the corect amount) and comp first do a comp test the bad cyl may show low becous of fuel wash down make sure you have good spark a spark tester can be had at parts stor If all that is good it may be bad inj. (leaking) or inj. wireing holding inj, on to long As far as tune up pars go use honda stuff only I will bet it is spark proublem

^ Not for long at the rate you're going. Padding your post count is a quick way to get the banhammer.

Ok everything has been done. Misfire was due to valve adjustments, now my problem is I'm dumping way to much fuel and my spark plugs are fowling in two days tops. When can cause the car to run so rich?
