every tune up parts has been replaced. WHY oh why am i still hesitating when slowly creaping up in RPMs?

 

did you check timing?

 

yep timing is dead on..

*thinks*... can it be my MAP sensor? if so how can i check?

 

may be the MAP, but I would think youd be getting a code. Could be the dizzy cap/rotor.

 

i had the same thing happen to my h22. replaced cap, rotor, and wires. seems to have fixed the problem. oh yes i also put new plugs in.

 

I had the same proble wiht my b16 when I got it. Are you running a pr3 ecu if so your o2s might be switched all you have to do is switch the two wires that run to the ecu. or it will do that if you are only running 1 o2 with it.

Yep if its a obd 0 b16 its your o2 sensors. either bad or swapped.

 

the car is obd 0... and only has 1 o2, which was replaced recently...

hmmmm maybe i got the wrong o2?... i either got it for a 99si or a 90 dx crx... dont remeber... which do i need or are they interchangable?

yea there are no codes being thrown..


which cap fits this dizzy? i bought one that 99% fitted but had to cut a lil box out for it to fit, maybe if i buy the RIGHT one that could be it?..

if this helps it ONLY stutters when creaping, heavy or open throttle is fine

 

Your supposed to run 2 o2's not 1 and there supposed to be in odd paired cyls up in the header. Hondata explains this in their text on their site.

interesting, so basically your saying that the lack of my 2nd o2 is most likely/defintley the problem?

 

yes I had the same proble because I had my 2 02s switched around. I could be slightly giveing it gas and it would stutter a little then finally go. Or if I was on the interstate it would stutter sometimes. If I would go WOT or give it a little more gas it would cruise fine. I had no codes either. You need another o2 if you are running a pr3. or get it chiped and you can eliminate the 2nd o2 Also when I bought my o2 i bought on for a 91 integra ls as well as my cap. Hope this helps

That is precisely what my car does, and I'm running a single O2 sensor. I figured that's what it was. What chip do you use to eliminate the second O2, I'd like to use that in my ecu, as soon as I get my chip burner working well.

 

you can get a muged ripped chip it eliminates the speed limiter of 112 mph and also knock sensor, oil pressure and the second o2. You can get them programmed for lower vtec activation point and remove the rev limiter and increase your fuel maps. I have heard alot of good things about http://www.hyperducktuning.com/
I would stay away from ebay.
or just go to a muffler shop and have them weld you in a second o2 bung and stick a o2 there and run the wiring but I would just get the chip.
hope this helps

 

can't you just splice that single o2 sensor signal wire into 2 and run them both to the appropriate spots?

 

here is a trick that i learned on my b16 rex i had, i took and swapped the signal wire and the voltage wire around on the tps, no check engine light, and it fixed the problem, that also dosen't effect anything the tps is doing.hope that helps.

Thats what I have done, and it still stumbles at light throttle and has all the problems described above.

 

no you can not splice it you need to actually pin it to the ecu in the correct spot.

Can it be that simple?.. Any long term effects?..

If thats not the 'right way' to do it, can u link a resource to pining it correctly insomniac?
thanks!

 

here is a couple they should help!

Let Me know if you need any help with it.

no effects, i ran it like that for two years it all was the same and it eliminated the hesitation.It is that simple no effects on the way it runs

 

I woudl just wire it like it suppose to be wired then you don't have to worry about it.
your car though!

One of my employes has a crx b16 with one o2 and has never had a problem he has had the car for about 6-8 months. You should check the pgmfi main relay i have seen this problem before other than that the crank pickup in the distributor can be bad causing the car to some times be off timing at tdc..

 

so i was going to attempt the 'swapping wires' technique but before i did that i just wanted to unplug my tps and take the car for a spin to see what symptoms occur from no tps... and volia! no hesitation! car feels great.. now waht does that mean!? lol

BUT the hesitation is VERY VERY intermitant, like it comes and goes whenever it wants to **** me off... So unplugging the TPS either FIXED it or just hid it a little longer..
what do you guys think about that??

 

well the tps is there for a reason so unplugging it just hides the prob.

the tps on my motor I THINK came from a d16 90si motor... are they interchangable?

does this mean my TPS is bad?
