NEED HELP ASAP

[Black4DrEK]

I just want to get EVERYONES opinion......

I have a 99 civic with B16a and a few mods...

Ok well when im driving it wont go past 5,000K or even really even hit Vtec... it just boggs down and sputters..... Soo i got scotty to try to tune it at Mainstream.. and it is Running really LEAN after it goes past 4200K., it just breaks down and makes NO power AT ALL:eek: ..... We changed the Fuel pump... checked the fuel rail... checked all the Lines for damage........we cam up with NOTHING:no:


Now i am about to change the Fuel filter.... BUT WHAT DO YOU GUYS THINK IS GOING ON!!!??????? please help, thanks....

[seanrg1116]

the fuel filter should have been the first thing done on that car. my :2cents:

dumb question but r u throwing any codes

[Black4DrEK]

no codes are thrown...

[JEY$JDM]

i would have guessed the fuel filter also... my friends car was doing the same thing just about. fuel filter fixd the problem. gl man. clean ass foe doe btw...

[Black4DrEK]

thanks^... i just put the new fuel filter on , its still kinda doing the same but.. scotty said the way its tuned If i fix it it will run really rich sooo ,, I think it might be fixed now it could be running rich....

[Black4DrEK]

bump.. anybody????

[slostang]

cat converter?

[TEG90]

injector? ecu? ^^ cat ? could many things. has it done this recently or has it always done it since the swap?

Check your oil level. Vtec kicks in at that area correct? We get people in the shop all the time saying their car wont rev high and loses power. Well, there isnt enough oil and the vtec solenoid recognizes this and wont allow the car to rev any higher. Make sure you are full of oil first.

-Ant.

[Black4DrEK]

It was full of oil.. and yes it just started doing this after the b16 swap... i use to have D series and never had this problem... and NO i dont have a Cat.. straight pipe.... its not the ecu..< scotty would have known that.

[Black4DrEK]

I cant figure out the PHUCKIN PROBLEM:dunno:

[firstgensir]

is the car obd0 or obd1.you sure you have the rght inj.if you use the wrong inj the resistance in the inj are different and would cause it to run ****y

[Black4DrEK]

they are the injectors from my SOHC.. ^^

[allen8603]

did it do it out of nowhere or did you work on it and then it happened?
ive seen reverse wired injectors do very similar symptoms before when wired 4/3/2/1 instead of 1/2/3/4
you need to get a multimeter and the specs for all the sensor ranges and start probing.

it definetly doesnt have anything to do with the oil level or vtec sensor though. thats obviously coming from someone who doesnt work on hondas. the vtec oil pressure switch is what he is trying to speak of not the solenoid and even still, if you have low oil, you can rev the hell out of the car, vtec just wont work because of lack of oil pressure.

[Black4DrEK]

I dont know.. Im just gonna take it back to my guys at mainstream.. or honda specialist on tara blvd... cuz im tired of F'n With IT.

[osnap]

id change the injectors and see how it reacts...

[Black4DrEK]

:no: Tom at honda specialist looked at it. we put a fuel pressure gauge on it.. it is reading 80psi:eek: WTF way to much!!!. Still EVERYONE IS STUMPED!!!!!!!!!!!!! WTF MAN!!!!!

[SixSquared]

check your map sensor? intake filter clean? osnap was having a similiar problem and it turned out his timing was slightly off. There was something else wrong, too, but to this day we don't know what. Something involving the intake, because he brought his car to our shop for bodywork and it sat for a while. Being nice, I gave him a new intake and filter since I had the stuff laying around. Problem had fixed itself by the time he came to pick it up.

So... I would say..

1. Check MAP sensor.
2. Check air intake for leaks/replace or clean filter
3. reset ECU
4. Check timing

That's the only stuff I can think of, because like I said osnap's b16 was actinging similiarly, and once those 4 things happened, it was golden.

[Vteckidd]

80psi is way too much, should be 40psi tops at idle if you have a stock regulator on it.

Sounds like a timing issue, triple check the timing belt an make sure everything is lined up. If the timing is off it could throw the a/f way off and make it not want to rev out.

I highly doubt its an injector problem.

[Black4DrEK]

yea i know that 80 is double the psi.. ^^^timing was checked before trying to tune it.... im Phucking tired of this Damn car!!!

[Black4DrEK]

O yea and it has a brand new air filter also...

[southside]

Now I see why you dont run your car....I be seeing you with Jim Brown all the time but never seen you run.

[Black4DrEK]

i know man it pisses me off , I want to run but i CANT!!!!!


IT has to be a Mechanical problem or somethin....should i take it back to the people who did the swap or what.....?

[SixSquared]

check your header/cat/exhaust to make sure nothing's clogging your exhaust?

[Black4DrEK]

^^ checked!!

[Black4DrEK]

OK i came up with maybe a solution... Im thinkin since the Fuel pressure is reading 80psi (way too much) maybe the fuel line from the rail is too SMALL.. maybe i should get a bigger hose...


What do you guys think about that???

[SixSquared]

Try it... worst that will happen is it still won't work and you'll only be out a few bucks for a hose... start small then get big when it comes to repairs... no use replacing an engine because of a bad o2 sensor, you know?

[Black4DrEK]

yea... its deffenently a fuel problem tho.. so ill just do as much as i CAN

[EmminoDaGreat]

fuel rail, get another.

[Black4DrEK]

^^ get one for me.. U gave me this ONE

[EmminoDaGreat]

I didnt, someone did tho, Ill see if we have one laying around, I think someone grabbed a fuel rail w/o a hole in the fitting on the end to allow fuel flow.

[Black4DrEK]

ok good.. i think rob was gonna do the Hole thing on mine... i need this sh!t fixed:eek:
