hi all,

my engine is suffering from killing spark plugs due to overfuling and causing a missfire on that cylinder.

its just been mapped and had no issues on the rollers, but no4 is fouling the plug and causing it to run on 3 cylinders afer a while.

what do i need to be looking at to sort this?

its had new plugs al gapped correctly, the engine runs on omex 600 and batch fires the injectors ive swap them over and the fault has stayed on 4 so its not that.

the spark seems fine from the leads.

whats next to check?


engine is a 1600 sigma that has been turbo charged

thanks

Going back to the mapper....

didnt realise they mapped each injector?

Im not saying they did but...
If its only started since coming away from the rollers/mapping session then it 'may' be something they did. As soon as you start fiddling they can distance themselves from any issues.

but nothing they do would cause the symptoms i have as far as i can see

Are you 100% sure its fuel as my car started fouling and killing plugs on number 3, turned out it was burning oil in that cylinder and ultimately cost me a bottom end rebuild, can't really see how mapping can cause only one cylinder to over fuel,
