Hi all, after some code guessing last week I purchased some new Kazama Auto ignition coils (red ones). After installation, and driving about 30kms, the car developed a misfire. Last night I identified it as coil number one. I unplugged each coil to find the faulty bugger only to realise I could do the check with Nisdatascan. First time round I didnt apply any dielectric grease. So, last night I went ahead and applied the grease to see if it would rectify the issue; this is when I found the boot on one of the coil packs appeared to be disfigured at the tip, probably from heat-damage (see pic). I then went ahead and dropped in one of the old coils which appeared to rectify the issue, at least for the five mins I ran the car for after. Now, I'm looking to return the coil pack and preferably get a single replacement for the dud, but it would help if I could explain why this may have happened? I've bought cheap coils before that have been dead on arrival but wouldn't expect this from a name brand - despite they're probably less-than-OEM quality. The engine and ECU is stock - there is no third-party wiring apart from for the AT-MT swap. I checked the harness in the wheel arch for damage - as the car is low and running larger wheels - it's visually intact. The ignition coil harness appeared to have been replaced by the previous owner. I replaced the plugs this time round. Just FYI: the coils didn't need replacing in the first place, after getting intermittent error codes which seemed to clear once they disappeared from the dash, I guessed it may have been the ignition coils. Actually, it was code 17, for the TCS motor to which I've got another on the way now.
