Question about 1990 Nissan 300ZX
Smoke is coming from the catalytic converter and the back of the engine. it sounds like that its misfiring but I am not sure. Any help would be greatly appreciated
Chech the ignition timing first.usually nissan vehicles has an ignition timing of 10 degrees before top dead center.after that clean or replace the spark plugs.use only unleaded gasoline.
