i started the car this afternoon and it imidetly started missfiering, so i look at the plugs and all but one are perfect.... i look at the coils and one of them has a section on the side partialy melted! what the hell??

 

is this normal?

 

Doesn't sound normal. What are your mods? Do you have a mini-battery?

 

fp green, hks 264 IN 272 EX, ets UIP LIP , samco turbo inlet hose with blitz metal filter, hks DLI, greddy profc specII, TBE whit test pipe, FIC 750 inj , and yes brarille 15lb battery

 

If I can remember right, someone on here had their wire harness burnt and it might have been related to their mini battery. Something about the ground.

 

Post pics!

 

thats one of the **** Happens times, I happened to me 30K+ miles ago. I just replaced it with new one and no issues since.

 

I've seen a couple do that. It's not unheard of, I wouldn't say its 100% normal either.

 

i'll post some pics tomorrow....

 

Check the wire harness for the coils and the DLI very closely. See if there are any wires chaffed that may be touching metal. If the trigger wire is shorted to ground it will melt a coil like that. There is also a possibility that the DLI has an issue and is causing the issue. If you have a misfire with a new coil installed, bypass your DLI and see if it goes away.

Good luck

 

were the bolts on the coils tight? maby a loose coil pack and wasent making a good connection

 

I have a set of coils for 150$ shipped, let me know if you need them

 

yeah the bolts to the coil were tight and i already changed the burnt coil.
the car is fine now, no misfires or anything but i still what to make sure that i don't have a bigger problem causing this.
i did check the DLI harness for any exposed wires or anything else but nothing.

 

any opinions?
