97 Bad Coil?

We've had this happen a few times -- the car idles rough; like it's missing & the "check engine" light comes on. It's only happened when it's been raining or we washed the car.

We took it to the repair shop & he said the code reader said "missing on #4"

he said that this type of coil has "issues". He also said the replacement coil may get this same problem later on.

Is there anything I can do to protect the coil from being damaged again? he said it was a 'well known problem' with these coils....

Thanks

Coils are within the normal realm of things that fail on a car. I've changed a couple (not in Subaru's) over the last 30 or so years. There's not much you can do that the manufacturer didn't aready do. I'd just change it and not worry.

I would first check the ignition hi voltage wire connections where they go into the coil. If they look ok then change the plug wires unless there fairly new. The tip-off is the rain or washing causes the problem. If you like to experiment wait till dark. Start car open hood and spray wires with water and look for hi voltage leaks. ed

Really? I've only had to change one -- and it was frm a cracked neck becuase I wrenched on it too hard..

Hmm. I've had cars where stuff is 'bad' and that's why aftermarket existed.

Did you want opinion or an argument? I didn't lie when I said I've changed a couple. If they didn't fail, I guess the local parts store wouldn't have them in stock.

Given that the coil has to supply a very high voltage spark under conditions of moisture, vibration and extreme heat, I'm surprised they last as well as they do.

Aftermarket exists for a number of reasons. My experience is that quality is pretty low on the list.

No argument from my end.. I'm pleased to get opinions... I'd just never heard/seen it happen before except from when I did physical damage. I'm suprised; but relieved that others have had problems -- which makes me feel better about buying a new coil pack.

Sorry if I came off poorly.
