Help! Sparks between distributor cap and spark plug wires!
Here's the problem, I'm seeing and hearing sparks right where the distributor cap meets the spark plug wire for spark plug 1. The spark is coming from under the rubber of the wire.
Also, when driving, it seems to bog off the line, and I'm hearing pops from my exhaust, I normally hear pops from my Borla, but not to this extent. I usually hear a pop when switching gears or when letting off the gas, but now, it's just popping at idle. Last thing, it's alot worse when the car is cold, I'm starting up for the first thing in the morning. Anyone know what's wrong? And how I could fix it? Oh yeah, MY99 OBS. 120k km (~70k miles). Catback exhaust w/Borla Turbo muffler. Removed snorkle. K&N air filter. TIA

Forgive me if I'm wrong, but we don't have a distributor, much less a cap for one, right? Distributorless ignition...
You have a cracked boot or a cracked coil pack, unless it's just loose. Check if it's loose, then pull the wire off (engine NOT running) and examine things. If all looks well, apply some dielectric grease around the inside of the boot and reinstall. |

Switch two spark plug wires, if the sparks follow its the wire. Im willing to bet your coil pack is bad though.

Should be simple to diagnose, as we have posted.
Brings up a good question, is an aftermarket coil pack worth the dough for a stocker? |

If you can find someone who makes an aftermarket coil pack for the Impreza, let alone any newer model Subaru, I would be very suprised. MSD didn't touch the old school late model Impreza (97-01) as they said something to the effect of the stock system being better than what they came up with .

I don't want to hijack the thread, but since you guys are already here, I have a question.
When doing a tune up, do you have to change the coil-pack, or can you go with just new plugs and wires? |

Just plugs and wires. A "real" tuneup would consist of checking the coil packs.

Pre 97 systems can use an external ingitor, like the MSD DIS-2 but later units have a combo unit.

Stickee: a coil pack will run about $150, so you don't want to replace it if you don't have to.
