I'm having issues with my truck running rich, I'm unsure if it's constant or only when warming up, it sure has quite the fumy/fuely smell to the exhaust, even after sitting for 15 minutes warming up, it still has quite the misty and foggy exhaust. It doesn't burn oil or coolant. After driving on the highway a bit, it stops smoking and the smell really dies down. I have quite a vibraty idle at 550-650 rpm, from what I read, many say this is normal. Truck seems to run great with a lot of power.
I posted a little while go about this, but didn't get a lot of help, thats okay, but I'm wondering if it could be a fowled plug or something, I was told that my P0420 code meaning bank1 catalytic converter failure was not my cause of the engine running rich but was CAUSED because of my truck is running rich and I need to identify why it's running rich.
Having this P0420, I will have nissan change out my catalytic converters. I could understand that having a bad catalytic converter wouldn't make the truck run rich, many run their trucks with no o2 sensors even plugged in without issues, just have to deal with the ECM constantly throwing a code.
I cleaned the MAF up real nice, looks good. Checked my vacuum hoses and they seem fine, all my fuel lines and coolant lines look fantastic... I'm lost guys!
thanks
