I need some assistance from the al-mighty G35 Driver Forum Engine Guru's.......last week I fried a coil-pack..first pic shown below...not sure what caused it...all of sudden just happened.....I had a cylinder 1 mis-fire..limped home and pulled into the garage....went ahead and replaced my OEM Cats since I found out that my honeycombs were blown out...then diagnosed back to cylinder 1 and replaced the coil pack..problem solved and engine was running great again.


Last night coming home samething happened.....limped home pulled into the garage and sure enough clyinder 2 misfire now.....Pulled off coil-pack and what do you know.....Fried coil-pack 2 now....so in less than 8 days I have now fried 2 coil-packs...

I dont know why this is happening and I wanted to find out if anyone has ever had this problem or maybe what is causing this? I have considered on replacing my spark plugs and doing a full tune-up on the car.....


Coilpack 1 - Bubble on the inside of it is fried.




Coilpack 2 - just pulled off and same bubble just not as big.



your thoughts would be great!

 

I believe I figured out what is causing the issue....determine that my front grounding point on my engine had for some reason..lost its bolt. I had 2 wires that were not grounded out...

 

There are so many things that it can be bro. I also blew 2 coil packs a couple of years ago from some moisture getting into my ignition system. It was during a time that it rained non-stop for like a month straight. But it can literally be anything along your ignition system.

 

Yup, that would do it.

 

Hopefully that solved it. I've heard of people having this happen with loose wires but normally with the ignition wires and not the grounds.


Let us know if you have to buy another coil... (that would suck)

 

what sucks even worse tonight upon installing the new coil packs the damn cylinder 1 coil pack bolt snapped off......so now I am probably going to have to get a new damn valve cover.....passenger side one....

 

you will be ok. Get an EASY OUT set. Use the largest drill bit you can without rubbing the threading, then just throw the appropriate easy out at it. You'll get it out no problem.

 

do they sell those at home depot or what?

 

Ya, you can/should be able to pick them up at any Checker/Autozone/NAPA as well

 

okay cool I will run up there first thing in the morning.....

 

so did you find out how to fix your problem i have the same problem is driving me insane please help me i have a turbo g35 and i dont know how to solve my problem i have been replacing coils like crazy

 

at the end of the day the front timing cover ground point wasnt the cause...fixed that and still blew coil packs....I re-did all my CAR AUDIO Wiring.....didnt fix anything...re-did my trunk lighting and that wasnt it...my last test was the capacitor I had...I removed it and sure enough I havent blown a coilpack on my car since. I sent you a pm back as well "DRAWGUN"

 

I send my car to mike murillo motor sports and they found ou that my culpprit was the ecu I was using turbox utec . I watting for a replacement but not sure if that is the problemi still think is something to do with my valve cover let me know if you find out was causing your coils to fry 210 290 -5190

 

I ended up fixing mine....was related to my capacitor going bad...

 

hotrod had the same issue fryin coils. it was the ecm.
