ok so here it is, i just swaped a b16a obd0 in my 91 dx, and well i ran into 2 problems... ok so #1 vacuum diagram.. i dont have have a vacuum nipple on my trottle body that goes to the lower nipple on the carcol canister. or do i have a dashpot on the trottle body, my map sensor is on the top of the trottlbody. .. any body know where i get the vacuum line to go in to the carcol can? i guess the tb is off like a 99 si b16a2... #2 problem, i got the motor running and all but sometimes when accelirating it stumbles pretty bad and if you rev it a lil its fine. but if you drive normal and soft it stumbles pretty bad and then it just kicks in like normal... anybody got any ideas? whould the vacuum on the lower nipple of the carcol can not hooked up cause this?

 

you can just get rid of the old map on the firewall all you need is the one map plug thats allready pluged into your throttle body. the charcoal can doesnt matter either infact people just get rid of those sometimes. just as long as there is no open vacum ports on the motor. for problem number 2 is your timing good? and are you getting a cel?

 

my timing is dead at 0.. i already checked that... and no cel light...

 

did you convert to a 4 wire o2?

 

no it is obd0 and i got the 2 wires piggy backed at the ecu to only one o2 sensor.. due to my headers

 

Which ECU are you running in the car? Is it always at a certain RPM when it kinda sputters if you will?

 

You need to wire up both O2's to the right spot on the ECU if you are running the PR3 ECU, don't piggy back them

 

i am runing a pw0, and it only happens sometimes while accelirating softly, but it don't happen like 3000 and drop the clucth

i have a dc header on it and only one bung. i know people that only use one 02 sensor. i just tired the 2 ecu wires to the one o2 sensor..

 

does any body know where i put the vacuum????? on the carcol can?

 

bump

 

well i fix the o2 sensor problem kinda.. i got a cat with a o2 sensor bung and now i got the car to run pretty good.. but i want all the vacumm... ANYBODY??? just tell me where to put the lines...

 

Just T off another vaccum port on the intake, all your charcoal canister does is purge the excessive HydroCarbons back into your intake so that your engine can burn them to keep the Hippies happy.

 

ok so i am going to take out the charcoal can out... should i take out the air purge on the fire wall? and does anybody know if it will affect the smog for next year... i live in nv.....

 

anybody?

 

if u live in nevada it doesnt matter just cali are a$$holes
