Misfire
 

Hi guys i have an 13b rotory enjin in my gx coupe datsun whas fine but started misfireing even when ideling hard to rev up to i conected an revcounter to one of the coils negative then the troubel started can eney one help i have checked for spark but realised al have sperk but the some of the plug leads i can remove no divrense but there is spark pls help

Check the plug leads to make sure they go to the correct plugs.
Leading go to LOWER Plugs and it does NOT make a difference to which plug,but if you want to be correct then look at the coil and place the lead at the proper plug.
L1 is Front Lower plug,L2 is REAR lower plug.

NOW Trailing leads NEED TO BE SPECIFIC..T1 goes to Top FRONT plug and T2 goes to Top REAR plug(closest to Firewall by the way).
Again the Coil will say that.

That IS if you are working on an FC engine which I assume.

hi i think so not sure and its new leads and are on the wright plase its non feul injectoin and some poeple say its the igniters on the distrubutor what i dont understand is there are spark but enjine rough and misses

did you check ALL 4 plugs for spark? the rotary engine uses 2 separate ignition systems.

Yes i have check there is spark on plugs but still misses and bakfire can it be the ignitors i am cleules i am at the point of selling this car

Ahh yes, shit doesn't work and i don't feel like learning how to fix it i'm just gonna sell it off to another sucker.......

Did you unhook the "rev counter" and see if the problem disappears since you said it started when you hooked it up

Have you compression tested the engine?

Replaced the cap and rotor?

Made sure your timing is correct?

Yes i did problem stay the same compresoin is ok when i remove te one igniter wires there are no divrince in ideling but the other one the enjin want to cut out

Are your igniters wired correctly?
