honda vigor 1990 , one cylinder does not work. it happened a few days ago and i felt that the car became trembling a little bit , I pulled THIS spark plug connection out and engine just nothing changed, but when i pulled any one of others, idle became much lower, i checked the spark, 4 of them were perfect and just this one was in white colour. What happens to this? Is it a engine problem? please help, thanks!

 

Well, your not getting spark or fuel. Now you have to figure out which one it is. Try pulling the plugs out and putting them in the wires. Make sure they are grounded and crank the motor. If they have a good spark then you probably have a fuel problem. It could be a clogged injector (especially with a white spark plug). Try taking a stethescope or a long screwdriver and put it on the injectors. With the car idling, see if you can hear a clicking noise in each injector. If that one injector isn't clicking then it is either clogged or it has a shorted wire.

 

Thanks so much and i have to leave it to next day as my is sleeping and my garage is so near to his room.

Thanks

Yes i did it just now but i could not find the different. they all sounds the same


By the way, where is the injector? and where should i put the screwdriver on?

The injectors are on the fuel rail. They should be clearly visible, although I'm not familiar with Vigors. You can put the screwdriver anywhere on the injector really. You should get a manual for your car, that would help you diagnose problems.

 

yes i checked the injectors and they seemed all the same and no different sound,

any more ideas

Thanks

 

Well, did you check for spark yet?

 

White as in clean and shiney from no fuel, or white as in coolant burning. A blown headgasket can make a spark plug white with coolant. It will look almost corroded. Do you have any overheating problems?

 

yes i have checked the spark and i have changed a new one on it but still nothing happened

i find that there is a black round thing with black round cap on it connected whith hose, and also has wire connection, i do not know what it is. it is broken. maybe it is the problem , i fix it with the glue or i may change it

 

thanks for your words

no i do not have overheating problem
