Flat spots/misfire on VTS

[kiddy_vts]

I've changed my spark plugs and one was in a bad way so its made it better but I still have nasty flat spots but only when the cars cold. Any ideas what to try next?

No one?

Mines gay as anything sometimes before it gets up to temp, comes and goes though, no idea what it is, I tend to drive smoothly and not too fast before it heats up anyway

your lambda might be f*cked, i had the same problem and after goig through a rake load of sensors and checkin and replacin parts i got to the lambda sensor and as soon as i replaced it it felt like a new car and had no flat spots.

lambda is a good guess, also the map and the tps sensor can be at fault. And if its only doing it when cold then the air or water temp can also do strange things!
