Engine issue coils? coil pack?

[Losi_8_boy]

Engine light is on and I'm thinking it's either the coil leads or the pack?

Only thing I've touched since it started.

Checked for trapped leads and all are connected correctly.

Cheers

You say you touched it ? are all the leads in the correct order?

I swapped top inlets over but changed back as it was a 182 one not 172 and yes all in correct order.... Cambelt <4321> air box

The coil packs are quite reliable, more like the leads or injector funny how the engine sounds ok but the exhaust sounds like its on 3 cylinders.
