Hey everone I have a ke35 with an efi 2tg and it randomly starts spluttering then fixes up then does it again. just wondering what it could be. Only does it while driving. All help appreciated. Edward.

When does it splutter? Under load, while idling, clutch in, clutch out?

It only splutters when driving. In every gear. It does it a bit under load but seems to perform a bit better under load. Mainly when just cruising at a casual pace. I've replaced the leads, cleaned the air flow meter and the fuel filter is fine.
