my glanza has started to miss on full boost

[sa15cr]

It missing on full boost but if I lift the foot off and put it back down it goes ok and if I put the foot down slower it don't miss ether

So far I have changed

spark plugs

rotor arm

distributor cap

And my plug leads wouldn't be 6 months old

Anyone know what would be wrong?

[morgey]

Coil getting weak?

[sa15cr]

I'll change it to see if it helps

[parker85]

Change the spark plugs mate and see if that helps mine done the same a while back changed the plugs and no problems since

[sa15cr]

I have new plugs in

[parker85]

U tried a new king lead yet could be it

[Matt1878]

Sounds like leads / coil kind of problem

[sa15cr]

Will I have a coil ordered and should be here in the morning if that don't fix it all that's left is to change my leads but can't see it being them because were on put on about 6 months ago
