ok i have a 92 vx civic and i have a b18b1 in it it obd1 and i has a p75 ecu. I idles really weird when it idles i goes from like .900 to a 1.4 or 1.5. Does any one know of any vacum diagrams for that swap. Thanks

 

does any one know why it would idle so bad WHat sensor could it be which one would go bad most likley

 

check ur o2 sensor thats probably it, but if not it could be a vacum leak

 

i was thinking like the idel control or the other sensor on the trottlebody

 

Is there a check engine light? pull codes first....if no CEL, I would look for a vacuum leak...light up a smoke a blow it into the engine compartment...

 

did you repin the o2 sensor lead? the plugs all plug in and the car will run, but the o2 sensor lead is in the wrong pin at the shock tower.

did you close all the vac lines that used to go to the egr control module? how about the evap canister? this swap should take less than 5 hours to complete running...

 

what o2 sensor should i have for this swap.

 

02 how many wires should it have
