Message hello, i just got my car back from the shop where they had rebuilt my Z32 NA motor, after driving the car i noticed that there was a strong smell of fuel in the cabin, after checking for fuel leaks and vacuum leaks, i checked on the sparkplugs and noticed that the driver side plugs were hella black! and the passenger side were normal (all plugs are NGK brand new) i think my car is spraying way too much fuel on the driver side, if anybody has had this problem before please LMK or if you know what the problem could be? before the rebuilt the car ran fine
