Hi

I have a headache, the third cylinder does not seem to burn the mixture well.

The third cylinder when touching the mainfold exhaust is somewhat cold and does not burn like the others. I have checked spark plug coils, even I have exchanged them, I have changed the coil wires for new ones, and it does not work as it should.

The exhaust backfires as if it didn't burn well. I've looked at the electrical diagram, and I think the wires go straight to the ecu, but I'm not sure. Can anybody help me?

Thanks.

These are the cables:

Here the electrical diagram.

The black / white cable goes directly to the ecu, I don't get along very well with electricity but I think it is. When it reaches the coil connector it turns white / green.

Any ideas?

Thanks.

I'm sorry I didn't provide that basic information. He was somewhat upset.

It is already solved, the problem was a spark plug .....

Yes, when checking them by changing the cylinder, it opens me confused and opens the bad one again.

Yeah incredible, I even got the coil wire from the junkyard ...

I took out the coil and with a wire I checked that it had spark ... so I checked the spark plugs and coils again.

Thanks and sorry.

P.S:

You also provided me with help in my previous post about the forks, tomorrow I will fix the seals, post some photos, it is the least I can do.

Here are my girls ready.
