Question

I have 2006 Infiniti G35 coupe it burns coils:( as I know ground wires can cause this problem..where is ECU ground wires? please help

Answer 1

do you have a coupe or sedan? has the car been in a accident? do you have any codes?

I would suggest you replace the harness and computer (you can get a used one just make sure it has the same number on it)

and also add a grounding kit (along with cleaning the factory grounds) lossen all the ground connecters clean them with sand paper on the connector and body and retighen the bolts back. 

 

There will be a few by the engine bay and will look like this lossen all the ground connecters clean them with sand paper on the connector and body and retighen the bolts back
