Angry Impreza - problems with ignition coils?


I posted this earlier but couldn't find this on the forum when i went to check for responses so i am reposting it. My apologies to those who responded.

About 2 months ago i started to have a shuddering of my car as it was driving, at first i wasn't sure if it was a transmission/engine/fuel injection problem. Then i finally heard a sparking sound under my hood and found a current jumping from one of my iginition wires to a bolt on the engine block. I eventually got my car in the shop and they found out i had a burnt out ignition coil pack which was replaced and my car is fine. The strange thing is that within 3 weeks of me having this problem diagnosed, my friends MY2000 RS had exactly the same problem and not only had to take his car to the shop once, but twice to get the same ignition coil replaced. Also to top it off, both WRC Imprezas suffered the same problem which led to Burns pulling himself out of the Rally de Monte Carlo. Whats going on here? Does anyone else have a similar problem with his or her RS? I'm curious to know.

The WRC Impreza I believe uses individual coil packs connected directly to the spark plugs, similar to the old Turbo Imprezas, SVX's and the new WRX. No plug wires( although the old "direct" coil packs were known to get a bit flakey as well). Just clarifying things a bit

FWIW, one of the Coil Pack's electrodes on my Mom's 98 GT LTD completely disintegrated with only a few thousand miles on it

I had my car taken in for that also (spark jumping from #4 terminal on coil pack to bolt beside it and #4 terminal corroded with a small crack in the insulator for #4) and they replaced the coil pack and the spark plugs. A month or so later I noticed some chugging starting again...I check and the spark is jumping again from the same terminal!!! (Though the terminal isn't corroded as badly since I caught it earlier) so this time I cleaned off the terminal and replaced the plug wires and I swear the power shot up noticeably afterward (it felt like it had been lacking in power for a few months before the chugging started the first time). Hopefully it was just a problem the #4 wire and replacing the wires will fix it.

Hello!
I've had this problem and it still feels like I'm bogging down. The dealer supposedly fixed this problem but I'm going to give your suggestion a shot. Thanks!!!!!

Have you guys try to put some dielectric silicon (I think that is what is is called.) on the terminals of the coil pack? Maybe moisture is somehow getting in there and making the spark leak out, eventually causing a coil pack problem because it is jumping to ground with higher/lower (depending on the situation) resistance.

Yup. Same problem here. With pictures. And yes, I put dielectric grease afterwards on it. We'll see if it lasts.

Actually, even after the dealer replaced the coilpack and plugs, about a month later the chugging symptoms came back. I checked and the spark jump and corrosion had returned (except with less corrosion since I caught it sooner). I cleaned off the terminal and replaced the only related part left (the plug wires) and everything seems to be ok so far, plus I swear the horsepower went back up (I thought it had been lacking lately). Apparently, it was a faulty #4 wire after all.

This post was a little old, but what the heck...
I too had a coil and coil ignitor issues. Both were replaced under warranty @ 35k on my 98 RS even with a Minnam Stage 2 installed.

I don't have many details, but would be happy to share via e-mail if necessary.

I too toasted an ignition coil on my 99 2.5RS.

Yes, using dielectric grease on the contacts of the coil pack.

And yes, I also had wire #4 sparking across. What a PITA...
