I just put on a 3inch exhaust and now my car is blowing black smoke sometimes.
I have been told my fuel mixture is to rich.
is this true. would resetting the ecu fix this problem? if not what would.

Black smoke does mean you are running to rich...and possibly burning some oil.

Resetting the ECU may help...but if all you did was replace the exhaust....hmm.

You have a HIGH-FLO cat on don't you? Or do you still have the stock cat??

i have no cat its just a 3" exhaust from turbo and muffler with a resinator to make it a bit quiter

and thats why you are blowing black smoke!! Hope your not driving this on the road near populated areas....NO CAT == TICKET!!

its only illegal if you get cought =)

i thought it wasnt illegal in florida?

"Even if you spend $20,000 fixing up your civic its still going to be a civic. My supra... well its a Supra."

If you just put a new aftermarket exhaust on it'll smoke... don't worry about this though it's normal. When they bend the pipes they have to lubricate the insides of them so they can pull the mandrel back out. The smoke is more than likely just the excess oil residue burning off.

so the black smoke isnt.."permanent"...?

well lets hope not... keep an eye on your oil level and hopefully the smoke will go away.
