You used your civic engine harness I take it?

Black smoke?

Can you smell gas?

i can smell a little gas but no black smoke , it revs fine but its sluggish and it spits and sputters when you try to drive it

oh and yes i did use my stock harness

did you change the fuel pump. i had a similar problem. bought a walbro 255 and its not sluggish anymore

i honestly would check your igntion timing... you might need to advance the timing.... due to black smoke you are having to much fuel and not enough spark for the delivery of fuel in the combustion chamber.... try checking with a timing light to make sure you are in the correct igntion timing.... that should help.... due to the fact that you do have a chipped p28 you have added more fuel and not more spark for the igntion of combustion. also if you have a fuel psi reg... try and turn the fuel pressure down a little.... but another way would be to get yourself and afc.... i have alot of good luck with afc... to fix the car from be sluggish.... any questions just hit me back.....good luck bro?????

well i think the problem might be with the P28 you are using. Sure its chipped, but is it chipped correctly. try using a P72 with a obd2 to obd1 harnest thingy ext... ask a friend or anyone. GOOD LUCK!!

ok well i got the stuttering problem fixed it was my o2 sensor,but i have a nother one when i got it fixed i let it run for about 5 minutes and it started white smokeing real bad out of the exhaust, and all i could smell was oil an it was missing, so i checked the spark plugs and they were covered in oil where the boot go's why is it doing that, and is that why its smoking or is it some thing else? what could it be
