Any ideas?

check your plugs

[Jim*]

Had an ignition overhaul around 5 months ago

[turbominicooper]

5 months of covering how many miles? i would check them again to be sure

[sa15cr]

My glanza done the same and I changed plugs, plug leads, rotor arm and distributor and made no differences so then I changed fuel filter and run injector cleaner thru it and seems to be ok now

[Jim*]

Probably 3-4k

I had a miss fire once on me starlet.

was a corroded and split coil pack.

I would be going back and checking dizzy cap and rotor arm and plugs also.

As above though had an ignition overhaul within less than half a year

Mine done exactly the same and turned out to be leads. I understand you say you had ignition overhaul but does do exact same as mine did.

[Flaminsam]

Mine misfired like that, turned out to be the coil pack split. Mine started misfiring at about 8psi of boost then just got worse from there

use multimeter to check the homes of the ignition leads

[Jim*]

What homes should they be? Where would you put the multimeter?

[5e colin]
