Hi Guys

I got a wired problem with datto, it doesn’t pull as usual pickup is very low, checked the spark plugs, cylinder 2 plug was wet and all the others were dry and white color as usual, so installed the wet spark plug to another cylinder and ran it and saw then it was dry , so assumed that all the spark plugs are ok ,my mechanic said that ignition coil is bad and leaking electricity, what is the best way to check ignition coil ?
later I checked the contact point it was ok, but rotor had a burn mark , so I sand paper it, still car has the same problem, suddenly for few seconds it pulls as usual then again like a tractor,
When cold start it has a misfire between 2000 -3000K rpm also but only once then after no more misfire.
So what do you guys guess? I want to 100% confirm whether it is really the ignition coil before buying it if not I am loosing 25 $. Or is there any thing wrong with engine cylinder, checked the exhaust tail it is black but no sign of oil burn at all, it is dry
Is wrong or faulty ignition coil will affect only one spark plug to be wet and others to be dry ?
Or is it something with distributor cap? Your help is extremely needed guys.
I got LUCAS Barrel type liquid Ignition coil it is older than 4 Years

Sumith, 40 years ago an old mechanic told me to wait till its dark, lift the bonnet and get someone to rev the car so that you can see if sparks are jumping anywhere.Give it a try.

Hi Ivan1

That is an great idea, i also thought it earlier actually i was planning this yesterday but i missed the chance, any way i am going to do this .

Thanks

Check the resistance of the ignition leads, can't remember the value they should be (far to long ago!) but you will notice if one is a lot higher value than the rest.

If its not dark enough to see the spark try touching all of the lead ends with the motor running, you will know for sure if there is a jumping spark!

Could be fuel not spark????

Sumith,
I don't think your country is famous for high quality fuels...certainly not in some regions.
It's most likely just a poor fuel issue. Maybe it is time to buy a compression tester guage.. They can be bought for between $30 - $200 at the auto accessories shops. Assuming you have them over there!?
It would be a handy addition to the tool box if you are going to keep "cars" as a hobby.

have ever you heard of "trial and error"
