I have a problem of intermittent misfire in cuore -06 both on cng and petrol. Below things I have already done
- changed spark plugs
- air filter
- checked distributor point gap, it is at .45 mm ( The point is used over 20K kilometers but no visible wear)
- cleaned distributor cover and rotor
The above things did improve the performance but the random missing is still there.
I also checked the spark plug wires resistance , from shortest to longest each one was showing 7.5 K ohms, 8K ohms and 9.5 K Ohms. This is within the factory manual specified range of maximum 15K ohms.
Also checked the ignition coil primary resistance it was 2.5 ohms , The factory manual says it should be between 1.35 to 1.65 ohms. My reading is slightly out of this range but I am uncertain since ignition coils dont go bad so soon.
What could be possible problem here??
