What i've got is a 2000 civic with a 2000(?) b18c1 and all that good stuff. Especially at low rpm's, unless i run the dogshit out of it, it'll kinda sputter and sometimes barely move. The check engine light is on and my air/fuel ratio guage (which by the way is an SiR instrument cluster) says its runnin rich. Ive had two separate diagnostics ran and nothing shows up. I always run the right gas, in which the mileage has gotten pretty bad. Does this sound familiar to anyone?...o2 sensor, fouled plug, need to adjust the air/fuel ratio...?

 

Your CEL is on and you had it checked and nothing came up?? Doesnt make sense to me.

 

Find out what code its throwing and correct it.
