my zafira 1.8 auto revs up fine when stud but wen under load at 3500rpm its goes in to
limp mode code read it miss fire on number one if i clear it it starts fine ticks over fine i
can rev it as soon as i drive off and get to 3500rpm it goes back to limp mode just wonder
if a coil pack can work fine on tick over but break down when under load.
Check your plugs when you remove the coils, they might be worn or fouled.
