em1 coupe blowing black smoke..?

[chindobaby]

hey guys just wondering if its normal for a b16a2 civic coupe to blow black smoke on high revs..? .. is it running too rich ?
need advice on what i should do if this isnt normal..
thankz..

It could be running rich,
It could also be a build up of carbon in the exhaust - usually happens if the owner/driver of the car doesn't push their car up in the higher rev range very frequently.

oh ok.. yeah thats what my mates tell me, i hardly push my car up in the high revs, i think maybe it is just a build up of carbon...
thankz mate!

mine is the same, if i dont VTEC it for bout a week, the first time i do it, it will blow smoke, but every time after that it doesnt...

[chindobaby]

oh ok..
will mine eventually go away ? if i just give it vtec more often?
then i guess if the smoke doesnt go away, it could b running rich huh ?

thankz guys..

just shit from ur engine coming out.... dont worry bout it untill it is blue smoke lol..

but if ur sereasly worried.. maybe try higher octane fuel.. and if ur car is modded without a tune maybe have it tuned as it may be running 2 rich or 2 lean...

hope this helped :):thumbsup:

its running rich isnt it, to prevent leaning out at hi revs?

B16a runs rich at high RPM to protect the engine. Almost all engines with aggressive cam timing and high compression do this with a stock ECU.
