hey whats up guys n chicks...i have a 91 ef hatch with a 96 jdm b16a OBD-0...I changed the spark plugs cap and wires..car is still making a sputter sounds n i can feel it also when im cruising on any gear...if i let the gas go alittle it sounds like its misfiring...i did check the timing and timing was off..but still makes that noise..its my first b16 and not sure if all do that or do i need to add a fuel pressure regulator...does it needs more gas????plz any help will help me with this stress....

 

Didn't extract this from ur post but did u or did u not fix the off-timing, how does it run then?

 

i did fix the timing..the ignition cam was off timing..but still makes the same sound and u can feel the car lose torque alittle but runs good when i add alittle more gas

 

anyone knows whats wrong with my car????it sputters when i keep it on a steady speed..

 

ummm....

have you changed out your injectors and or took a look @ your o2 Sensor?

 

i have the same problem with my B16a

 

nah not really...u think the injectors are dirty or clogged???what do i look for on the o2 sensor?dirt ??thanks.

 

BEEN TOLD IT COULD BE THE DIZZY...i changed the dizzy rotor n still does the same..can it be the dizzy???how can i find out if its going bad or u cant tell..

 

if its your dizzy, you will most likely be throwing a code when this happens.
Did you do a full tune up?

 

Ok, I'd do this, and I tell u this only because I had a similar problem and it remedied it.

Check the fuel system even replace a few things..

Filter
Injectors
Rail
All related line and hoses.
Also check your plugs, make sure their not fouled up and they have good spark.


This is something ur gonna have to find out through process of elimination, so maybe we can start there and see if it gets us anywhere.

 

I get that same sputter when im trying to cruise as well. Lets figure this out, once and for all.

 

Your valve cover isn't an obd0 valve cover. I think the obd0 ones are supposed to have a large "DOHC" with a small "VTEC" though i hear there are some that aren't. obd-0 motors were oldschool. 89-91ish ef motors and integra xsi motors. If your motor is obd0 it should be running a pw0 or pr3 ecu. If you are, then you need TWO O2 sensors. Alot of people wire the two o2 sensor pins into one o2 sensor for aftermarket headers n stuff. Check to see how many o2 sensors you got. Can't really tell with your small picture. If you got one, then that's probably the issue. If you have two, they might be wired backwards. Unplug both o2's and see if it drives better. If it does, then you gotta swap pins c8 and c16 on your ecu.

Unfortunately this doesn't really help the high rpm stuttering. You shouldn't need any aftermarket fuel regulators.
