Misfire?......

[matt 1b]

I wonder if someone could give me some guidance on a slight miss iv developed on my 172.

Now this only happens a few times each jouney, the car appears to slighly jolt under acceleration or when backing off and very slightly reapplying the throttle.
Idle is fine (well slighly lumpy but no rev hunting or dropping a cylinder) but thats normal and power seems fine. The jolt is only minor and not like a fuel cut on a turbo car with boost ceep or anything.

Im thinking plugs or injectors? I will check the plug quality and gaps at the weekend as to be honest no idea when last changed?

Any other ideas of common faults iv over looked?

Thanks in advance

worth checking your ht leads if your doing your plugs

I've had issues since the snow came. Off with my brother this week at some point to get fixed, usually alright when the weather is fair for a few days, hoping it's a simple thing.
