So i have posted a few things on here in the past few days. Built a 95 civic with d15b jdm motor. Have cold air intake and full exhaust including header. 2 1/4 inch header to 2 1/2 inch cat back. p28 and i wired the 4 wire o2 in myself. got it right on the first time. have the purge sol. plugged in and capped off since i chose to keep stock d15b intake plenum and head. the car runs great and roars down the road. Here is the issue. I am running way too rich. I have read that the p28 and this motor will work but run rich. I have also read that with intake and exhaust i should have bumped the air up enough for a proper a/f ratio. car also runs extremely cool and i think this is due to how rich it is running. i even put in a new thermo because of it. any thoughts on how i can fix my issue? I do have a p06 as well as my p28. Since my p28 works i thought it might be a better idea to go ahead and mod the p06 to vtec and chip if that is my only option since this is my daily driver and have no other mode of transportation to get paid. gotta keep her running. Help me get better that 24 mpg please.
