Smoke from Exhaust

[Calvo]

you will actually find that most vtec hondas run very very rich in the top end to promote in cylinder cooling and lubrication...also a safety mechanism against lean outs!

so its not too bad then? should i get it looked at?

If you are running a MAP sensor then everything should be OK. If its an AFM then that might be your problem.

how do i kno which one im runnin?

[poid]

nah a little puff of black smoke is nothing to worry about

The little thing above the throttle body/butterfly with the wires sticking out is the MAP sensor.

Excuse the foil

[Calvo]

yeh. i think i got MAP then.
like this thing?

engine bay shot:

Smoke coming out at WOT (wide Open Throttle) hence Vtec is normal, once the stock ECU senses this, it will make you car run rich. Honda did this to prolong the life of the engine, if you dyno tune your car with some sort of piggy back to correct your air-fuel ratio, hence leaning out your A/F curve, then most of the smoke would disappear at WOT. Also take note the colour of the smoke as someone previously stated

Black least worried
Grey/White - Worried... most likely a blown head gasket where coolant is mixing with your oil...
