Hi,

Is there anyway of testing whether a coilpack is on it's last legs...???

I have looked at them physically and they seem fine but i have had problems with misfires lately and was just wondering if there is a more sure fire way of testing them for probs...!!!

Cheers,

John.

Look at the primary voltage on scope. If the coil has a module built in and only a switch signal is available check the current ramp on a scope.

what should we be looking for exactly?
