Hi
Car got an intermitant misfire , normally 15 to 20 mins when fully warm, its 87 325 auto . but can nt trace it by pulling HT leads OFF ?iT SEEMS ON UNDER LOAD ie when driving

So far i ve swapped :-
the plugs, coil , cleaned the 2 tdc speed sensors on bell housing even swapped ECU over,
:cry:
Was thinking dissy cap / rota arm next , but would have thought if that would be doing it all the time ?
could it be MAF related ?
could it be a BAD EARTH some were?
any other idears ? :eek:
thanks inadvance

could be a poor contact on the dizzy cap and not the rotor,
