Okay need help ASAP as i have no job and have interview on monday morning. This an egine swap but dont know where to put my thread. This is a b20z2 so i am having problems with loss of power and stutterting on acceleration and exaughts spits on a full backfire, whenever the stuttering happens. I can shift in and out of gears to avoid it for 30secs to a min, then it stops for awhile there are no signs that i can tell that warns me its going to act up. I have used injector cleaner, recharged my k&n air filter, cleaned iac valve, changed fuel filter i was gonna change my tps but store gave me wrong part. Anything is helpful! Thanks guys!

 

what are the cel codes?

 

what car and what ecu ?

Has it ever run correctly?

 

I can only jump it atm, but when i do its a blink code of 43 which i believe is fuel system.

 

1995 honda civic dx. Yes it was running great then last tuesday or wedsenday it started doing this, no idea on the ecu as i bought it with engine swap and havent looked yet, tbh dont how yet either.

 

Okay so this the info (37820-p75-a01) i found on my ecu. according too al this: mine is one of these two:
P74/75: 92-95 OBD-1 Integra LS/GS
P75 : 96-00 OBD-2 Integra LS/GS

The way to tell if it's obd1 or obd2 is the plugs.

The thread I linked above has the pictures for you to see the plug differences, they are easily discernible.

 

Thanks for that link

Its
Obd1

 

test the coil and ignitor
my guess is the coil

 

Okay i will look into this.
Thank you.
