Unusual b16 ef problem
I've searched for literally 3 days all over the web so I'm finally gonna post here. My car has been doin this weird thing for over a year now. After driving for about 30 mins mostly if on hwy it kinda cuts out feels like a big gust of wing hits my car and sputters till I give it full throttle. It will continue to do this until I turn it off and back on. Then 20-30 mins later it happens agian. Well now it happens every 30 seconds to 5 mins. I hate problems like this cuz it doesn't happen all the time so its harder to figure out. I've replaced plugs cap rotor and fuel filter I'm about to order up a new walboro 190 even though it has one thats less then 2 yrs old but thats the only thing I can think of. But I don't wanna spend $100 and waste a few hours putting it in if it doesn't need it. What do you think?

Re: Unusual b16 ef problem
sounds like the ignitor inside the distributor is acting up possibly. have you tried another one by chance? and is your check engine light on?

I agree with D16, sounds like an ignition problem. What kind of shape are the plug wires in? My friend had a funny misfire problem as well and it ended being the piece of **** plug wires he bought at Auto Zone. Put my old NGKs on there and the misfire was gone.

No cel I haven't tried a new dizzy yet didn't wanna have to buy one cuz I don't trust the remans so I'd have to buy a new real oem one. Plug wires are stock with 65k on them. I'll order up some oem wires asap.

Cliffnotes: Check the little plastic screens inside your injectors. One was folded up into my fuel rail, pulling it out and bending it back fixed it. I still don't know WHY it would cause that sort of problem, but it totally fixed it.

Re: Unusual b16 ef problem
The constant speed stuttering that occurs in these cars is often due to the oxygen sensors being hooked up backwards. Try switching your two oxygen sensor pins at the ECU, reset it and see if it fixes the problem.
The oxygen sensor on a stock EF wiring harness will only connect to one of the oxygen sensor plugs on the B16. The one that it connects to is the wrong one. That is why this problem is so common.
The only thing is that this usually occurs all the time once the car is warmed up and you are holding a steady cruising speed.

Re: Unusual b16 ef problem
i'm jumping in the o2 bandwagon. should take 5 mins to check that before spending bucks, but the regular tune up stuff couldn't hurt. had the same issue with my obdo b16 in my ef, and i thought they were wired correctly, but i swapped em anyway and bogging dissapeared :D. depinning an ecu is easy too. worst comes to worst buy a cheap eyeglass repair kit for a couple bucks to get the screwdriver haha.

Re: Unusual b16 ef problem
Thanks alot for all the replies. I'm gonna switch the pins on the ecu as soon as get a chance. The only thing with that is it used to do the stuttering thing every 20 mins and now its gotten alot worse like undrivable cuz it does it so often. It is mostly at a constant throttle though so I'll try that out. I'm gonna check the screen in the injectors too. It really feels like its a fuel issue, but I guess I couldn't tell the difference between not getting fuel and the 02's being wrong a stutter feels the same

http://www.hondata.com/techo2problem.html everything you need to know about the o2 issue. read it and see if it's the problem you're having. straight from hondata's site so it has to be somewhat reliable

Re: Unusual b16 ef problem
check the eld, it's built in to the underhood fusebox, you can search on here how to test it, if it's bad you have to get a used one, honda does not make it any more, i would also replace alt at same time, this prob sounds sim to mine.. had it for years, just fig'd it out..i feel hella dumb.

Re: Unusual b16 ef problem
I used to have this problem. The most recent things i have done that seem
to make the issue disappear, is a new O2 sensor and I resoldered my Main Relay's dry joints.

Re: Unusual b16 ef problem
I'm not gonna have a chance to try the o2 sensor switch until saturday cause of my work schedule. But I'm devoting my entire weekend to getting this figured out. It seems like the more I research the more possible things it could be lol. I have a list of about 10 things to check. I'll keep you guys updated and let you know exactly what fixes it. Unlike all the post I've seen were the person never comes back and says what fixed it so the thread is worthless.

Re: Unusual b16 ef problem
UPDATE: So yesterday I went to switch the 02 sensors and realized I only have 1 and it in the down pipe so I don't know what to do about that. Also I pulled my plugs and they had oil on them from the old valve cover grommets I had on before. So I changed the plugs went and bought new oem wires took the car for a drive and it didn't do the sputter thing for the 30 mins I was on the hwy. So I was like sweet its fixed. Well last night I drove it around for a couple hours and it would sputter every 15-30 mins. Which is way better then it was before but still a problem. I'm gonna go test a bunch of stuff right now and report back.

Re: Unusual b16 ef problem
so you can't run a just 1 o2 on a obdo car or it will run wierd? I'm converting to obd1 and have a hytech header ready to go on so I'll just deal with the problem till I convert I guess. Not worth welding a bung into my old header if I'm just gonna take it off.
