ok i put a b18a1 into a 90 si crx and i got it running but it runs like **** its running real rich plus its like missing real bad on the bottom i dont have a o2 censer that might be the prob what could cause this i think i have a ll the vac lines hooed up right not sure i just want to get a input about it before i take it to the shop

 

Step 1: get an o2 sensor.

...

Step 2: use SOME form of punctuation.

LMAO!!

 

I second both of those steps

 

yall dont have to be a dick about it i was just asking ...................would the firing order cause it to do that

 

Maybe, fireorder goes 3 4 2 1 Cyl. 1 is farthest from the dizzy try putting in an o2 sensor first though.

 

timing....
firing order....

your using the b18 ecu i hope and not trying to keep the stock one....

what codes do you have aside from the o2 sensor? (check)

 

naw im using the integra ecu not sure what other code im throwing but like say if i run it down the road and a steady pace it runs good untill i gas on it or just kinda tap the throttle it seems like it gets ok gas milage but its running real rich it smokes but i know its flood smoke

I think you used all your punctuation up there.

Without an O2 sensor, the computer has no idea what is happening to all the fuel it's putting in to the motor. So to be on the safe side, it runs rich, in an effort to avoid engine damage. You need an oxygen sensor, and you're going to get one sooner or later. Put one in and if the problem continues, troubleshoot from there.

It wouldn't be a bad idea to see what other codes the ecu is storing.

 

ok thanks for the help i'll get one and see if it helps

of course it will thats why engines have O2 sensors..
