ca18det s13 melted coil packs? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Ok guys, I got a problem Just got my s13 back from being tuned on the new turbo (gt2860rs), and the car ran flawlessly for 2 days....great power, boost came on strong, no knock, etc. Thenwhile cruising, all of the sudden it sounds like my car has dropped a cylinder....sounded like a boxer engine. I pop the hood and I find the #3 cylinder has a melted coil pack, black goo coming out of it. So I got a new coil pack today and put it on there, and same thing...running on 3 cylinders, and the new coil melted after like 5 minutes. What the heck is going on? I haven't changed the spark plugs in a few years, and I know they are a heat range hotter than what I should be running on this setup....but still. Would a massively fouled spark plug cause the coil pack to melt? I checked the grounds on the intake mani, and the one on the coil harness and all looked good. Anyone have ideas on why this would happen all of a sudden?

No one has any ideas? I am leaning towards a bad ignitor maybe, from what I have researched.

Alright, well I replaced the ignitor chip and all my problems are solved. Just wanted to let you guys know what the resolution was in case any of you ever have the same problem.
