i recently swapped a '01 b18c1 into my '99 civic ex coupe.. everything went well but im getting like 170-185 miles per tank W/O SMASHING.. yeeeeeah.. everything on the motor is stock cept for a skunk2 mani.. running p72 ecu.. just wondering if anyone might know why it'd be running rich and why it'd be spitting non stop black smoke.. thanks

jaminonyourface

anyone?

Do you have a FPR or guage to see what you're pressure is at?

jaminonyourface

no i do not

Thagreybomber

That could be a start....that and a a/f ration guage. I'm not too sure on what numbers you should be running at, hopefully someone with some knowledge chimes in

Are you throwing any CEL's? Sounds to me like a possible bad O2 sensor or O2 sensor wiring.

Are you running a straight pipe/no cat?

jaminonyourface

no cat.. got a test pipe

Thagreybomber

no cat....that answers your black smoke. I was experiencing the same thing.
