There's no MAF in this one, so if nothing else, that can be ticked off the check list.
(It uses air pressure instead).

Checked usual stuff like connections etc but didn't have time to get a good look so put it to bed in the garage until tonight. It's a Zetec Silvertop turbo running megaSquirt. It sounds like it's running on 3 cylinders but there is no real difference when removing plug leads one at a time. Changed spark plugs around too but no effect. Fired up the laptop and had a look at the megasquirt dashboard. I noticed that the duty cycle gauge wasn't doing anything but can't remember if it did before. It's all black art to me anyway as my experience was with old school stuff. Any advice welcome.
