soooo my brother was following me home and i was in 2nd gear turning a corner then nailed it... he told me that when i did a cloud of black smoke shot out on his car..and yes i did search for this but i couldnt find anything...is this bad? and wut causes it?

 

you might be burning oil

 

it wasnt a constant smog of black smoke, it was just when i hit the gas hard one cloud of smoke came out. and if it was oil i think the smoke would be kinda white

 

Is ur SC boosted?? If soooo then the black smoke from the exhaust under a load is normal

 

no its completely stock 2j

 

Generally..black smoke means the too much fuel/running rich. If it was burning oil, generally, the smoke would be blueish/black.

 

+1 on too much fuel, but dont think factory ecu should let that happen..?

 

Do you drive fast a lot, or are you a very conservative driver?

 

mods to the engine/fuel system/etc? mileage? needs to be more specific

 

run a can of SeaFome thru the pcv valve rubber hose, that will clean things up....just youtube/search forum
