pulsar gti-r missing

[1200NISMO]

G'day

My gti-r is running like absolute sh##. At idle it is missing once every second or so. And when driving it misses a heap and black smoke is coming out the exhaust (which i assume is unburnt fuel).

Any one have any idea why it's missing and what i can do to fix it?

Check sparkpkug's wiring to them, mass on engine.

Everything that is used to spark.

Spark is getting to every plug still missing....could it be plugs?

[RobS]

is the timimg allright?

sparkplugs could be the problem, i had it with my racer, it sparked, but 15° to early, and one time the sparkplug was dead, but sparked

I had the same problem check

leads
spark plugs
throw injector cleaner through it

[1200NISMO]

how safe is injector cleaner....can it do any harm?

which is the best one to use?

1200NISMO - If theres fuel running through exhaust it could also be a boost cut problem. Maybe check the actuator hose if your certain of the boost your running.

I"d also check the plugs for fouling and or the plug gap. Boost has a tendancy to blow out spark when the right gap isn't used ( had problems with this in the past )

I've used a mobil octanebooster/injector cleaner solution in my R33 a few times, registered a 13hsp@wheels increase according to the apexi multichecker and didn't seem to harm anything.

Best of Luck

i'm pretty sure it's not boost cut related as it misses at idle too. will put some new plugs and injector cleaner in tomorrow see if that helps.
