If got a misfire under load Rev counter bouncing any idea people

It's had a new series 2 PCU that has been hard wired in, 6 new coil packs and 6 new plugs, the Rev counter is jumping around and the hicas warning light comes on after and flashes after about 10 minutes of driving around.

 

Any ideas?

 

Much appreciated :thumbup:

Was it doing this before the work detailed above was completed?

After replacing the foe plate

Flex plate lol sorry

After doing the flex plate it all started about one or two outings so changed all items as was going to still miss fire under load

I and the rev counter been jumping up and down since last hers heat wave

Rev counter is fed a signal from the cas unit as is the ecu to trigger the coil packs and injectors, would start at the connection for the cas unit first.
