Misfire

8 posts in this topic

On returning from a successful mot, I was rewarded with a misfire on one cylinder, it's OK above 3k but idling and tickover it's missing like a bugger!

 

Tank off and all looks to be well, I'm suspecting a coil pack or spark plug, any recommendations where to buy leads and coils, I'm going to give her a good service while I'm in there too as it's been 12 months since the last one.

What's it like running with the lights out? Any light shows? Any sign of tracking on the plug ceramics?

No lights on, I've not checked the leads yet as I haven't had chance to get in there.

No, I mean looking under the tank in the dark, so you can see any sparking.

Tank and airbox off today, everything looks as Honda intended, no tracking across any HT leads, coil pack connections are pristine, plugs are fresh and gaps are OK.

 

All back together and the misfire has gone? Time will tell if it reappears, I hate not finding ding the fault.

Maybe a good run and a fresh tank of fuel ! or 1/2 a tank depending how flush you are may be just what she needs !
