Ok this I have not been able to solve whatsoever although I've asked it on numerous boards:

I am running a 1st gen B16A in a teg with 5 speed tranny and automatic PW0 computer. I got an MSD cap and coil, new plugs (gapped properly), new wires, new rotor. Now, when I am just lightly accelerating or holding a constant speed around 100km/h (60 mph) (note: the car is reving about 3000-3500 rpms) I get this bog between 1800-3000-3500 rpms. I sounds like water boiling but coming out of the exhaust. I don't know if I can describe it any better. It goes (don't laugh) booo-bo-bo-bo-bo-bo-bo-booo. Sometimes the car does that slightly at idle too. If I press on the gas harder it doesn't happen. Anybody had this kind of a problem???

 

even though you told me not to laugh i still did. i couldn't help it.

but about your problem. i don't know what it could be. sorry

 

thats nuts examine your ign. you need an msd system not just a coil.

 

no this happened way after I put on the coil...

 

have you tried using a manual ecu?

 

don't got the dough to but that i'm thinking might be a possibility but it didn't do this for the first few months I had the setup

 

Yeah, switch to a manual ECU.

Just for some added info. Do you have an aftermarket exhaust? Does it make that noise when you let off the throttle?

ya....i dont know if thats too simple, but that noise hes talkin about on some aftermarket exhausts where it gargles when the throttle is let off. . ig ues it could sounds like "boo bo bo bo bo boo" heh

That's what I was talking about, but I kinda wanted to see his feedback before I posted anything. My exhaust does that **** all the time. It's loud as hell and my friends call it the "ghetto mIsfiring system" (refrence to Initial D) lol

 

Check your ignition timing.

running rich is what usually makes that "gargle" its burning all that excess fuel.. that's one occurance of booo.. boo.. boo (LOL)

 

bo bo bo is just ur car running rich

the (bahnnnn bahn bahn bahnn) sound is probably cause cylinder head is dirty. I had this problem before and I don't even know if that's how i fixed but this is what I learned:

take out the spark wires and plugs, then get a long and thin metal made stick with a sharp end and clear out the rings u see from top of the head (but more than half way inside the cylinder wall). I'm sure you'll see nasty oil around those rings. just remember though, do clockwise around the walls and make sure you don't scratch em. once all the oil is out or most of it just get silicon grease and put lil bit on the plugs see what happens. Maybe this can be off but it helped my problem.

oh yeah btw not askin to take off the head to do that

 

forgot to mention: reason to use a metal sharp piece is so if you tend to drop the stick inside the cylinder, u can still use a magnet stick to take it off without taking the whole motor apart. I do this once every 3 weeks and I enjoy it

 

instead of beating around the bush going from site to site. why not just go to the source of vast information available from michael delaney and team-integra.net. just a thought.

 

**** i never thought i'd get so many replies...thx guys. Ok to address a few things:

the fartcan stuff...that's not it. its coming from the engine not the muffler. yes the engine does fart especially when I shift at high rpm. The cleaning out the cylinder head i'm gonna try that thx Typico512 ... about running rich and buring fuel ... I get 360km on a gas tank down from 500 I used to get with the b18... so that might be it but as i posted b4, the car seems like it doesn't have ENOUGH fuel pressure. According to the helms it should have btween 48-52 psi mine has only 42 with the regulator disconnected... but i will go visit michael delaney thnx 4 that too.

what about the icm? could that be a problem???

 

oh yeah ....how do I go about leaning out the car?????

...is this a serious reply? Use a metal stick to scrape the cylinder walls? I must have missed the build-up to the punch line...

 

Are you utilizing 2 oxygen sensors or just one?

A lot of hesitation/low RPM stumbling problems on pre-OBD cars (PW0, PR3 ecu) has to do with this. Check here for more info:

http://www.hondata.com/techo2problem.html

 

When I was running my auto OBD2 PR4 ecm, and a wideband, I found that the car was idling disgustingly lean (18:1) at idle, and then very rich in the midrange, until it tapered to 14.7:1 at the top end. I changed to a manual, OBD1 PR4 and it works very well now.

 

no no no

not the walls, the ring under between walls

 

ok....I am running 2 o2 sensors...i'm gonna try what they say on the hondata web site. I also got an a/f gauge so ill see if i'm lean or rich when this happens i'm gonna see if converitng my computer will help

question i read on a web site that to convert the pwo computer from auto to manual all you gotta do is resolder jumper 37 to spot 36 or something like that...does that sound right? is that all u have to do?

 

change to manual obd1 ecu for that engine...I don't remeber the part # but you can look it up on the hondata.com website

huh?

 

ok so i figured it out i got a fuel pressure regulator and I turned up the pressure about 10 psi and it aint doing it anymore now it accelerates clean ..... at least for now
