Soon after buying my old car I got a misfire, sometimes just the one cylinder but occasionally two. Tried what I knew at the time to narrow it down but it wasn't until a kindly soul from London and his friend Rover54 came to the rescue with the remote T4 that the fault was diagnosed as a EMU problem and I got a replacement ECU kit from eBay. But mine had multiple misfires unlike yours and present just about all through the rev range.
Still like the idea of IMG failure esp. considering it clears at higher revs, but with no evidence like a "washed" plug it's difficult.
Shame the remote T4 project received such hostility as anyone worldwide could have benefited, still I've got Toaf and am grateful for that - as I still am to the guys who helped me out back in 2013.
