I have a 2006 350z I just recently put a momentum turbo kit with a haltech platinum plugin play ecu and we can get the car to crank and run fine but after about 15-30 sec the number 3 and 6 coils and EXTREMELY HOT to the touch but it's only those 2 we have replaced the coils and it still does it I've read it could be a ground issue looked at every ground cleaned them put them back on, put new spark plugs in, bought a grounding kit, turned the dewel time down to 1ms done everything I could think of still burning coils so if anyone has an idea or ran into this problem please let me know trying to get it running for my buddy before he gets deployed thanks!
