Have a 1.6 CVH XR2i with the EFi that keeps cutting out. Starts perfect from cold and runs for varying times but when hot will cut out. If moving will sometimes just stutter, then go again but other times will die and refuse to bump start. REV counter drops to zero even if cars momentum is turning engine still.
I suspect coil pack but tested out ok with multimeter and last time I called AA the car refused to cut out for the 15 minute AA was looking at it even though it had cut out and failed to start before I rang them. Also AA mechanic said these older coil packs do not have a memory so the trick of unplugging control plug for a minute, then reconnecting should should have no effect, but this works every time ???
Long winded but wanted to give full picture, and cannot try a a known good coil pack as current one under warranty (6 months old) so if at fault AA must replace.
