Hi, ive alredy used search but couldnt find anything to help,
ive just fitted COP ign and the car is misfiring, ive followd the 1.6 wiring posted and put the 100k resistor in(running mspnp ), i couldnt get a 10k capacitor but ive fitted two 4.7 instead, the problem is that not all the coils spark , ive tried swapping coils but its still the same cyls that spark, at times its not even the 2 coils that share trigger wire that dont work ( 1 will and 1 wont), the coil that does spark isnt always on the same cyl, it jumps around.

Before i fitted the cop, the car missfird on 2 and 3, thaught it was the std coil ( 2nd coil since mspnp) , any way of diagnosing if its the ecu ?
