My Brothers Pulser started to miss fire yesterday,
But before hand had been running fine all week, and last time it was booted was 2 fridays ago.

So he removed the plugs, and the tip was missing on cyclinder 1 plug

And we know its running 11.8 - 12.0 :1 AFR, as he's got a wideband fitted, and he sed he was watching it last time he gave it some wellie.
And there's NO DET at all.

He's running HKS plugs, which he's never dropped or damaged them in any way.


Has anyone had similar problem?

All i can put it down to is a faulty plug, or injector is failing.
