I HAVE SEARCHED, results dont match what my problem is....

Mainly my car sputters on and off, it was perfectly fine until dismorning when it's decently cooler outside because of rain, anyways, when the car's warm and i've driven it a bit, i stop and revv it, it'll hessitate slightly when i revv but when i drive it's perfectly fine, but when i give it gas and go to speed or race it'll sputter and buckle pretty bad....

i dont know why it's doing this, but the way i fix it is to find a nice piece of road, revv it up, and drop the clutch, smoke the tires and take off, most the time that fixes the problem....

but whats causing this guys, it's annoying as hell and always happens when i've planned to race someone....

i know my car's not scared, so what the heck!...

BTW the car is right from japan and my dad said it might not be used to the weather and humidity here, what you think?...

So you're the guy who drives around the city like a punk all the time..

Looks like steve managed to sell the car to someone else who drives it exactly the same way.. did he mention to you that the motor in that car is not the original one?

looking back at all your posts, I can come up with a reason why you seem to have several running problems with your motor and clutch... It's called abuse and neglect..

if you havnt noticed as well, it's been pissing rain all day.. you say that this problem just showed up today.. and that it seems to happen anytime you want to race ... here's another hint.. quit racing around on the wet city streets like a clown.. there have been enough accidents on the roads already...

Icemark

have you done the basics, checked TPS, Checked the AFM, Checked plugs, checked for error codes???

, ah yeah right... more than likely the engine is just warmed up after driving like an idiot.

The weather and humidity in Japan is worse than the weather where you are. Your dad knows nothing about these cars, right???

Archangels

my dad was just giving me a guess out of the blue....

and how the hell do i drive around like an idiot, it's friday night and there is a track in the city buddy....

abuse and neglect my ***, i take car of this car perfectly fine, always checking and changing the oil, coolant, the works.... for one my one thread i made about the clutch, that was the second time i've launched it hard.... i'm not racing around the wet streets **** head i have more brains then that, nor when there dry, the weather was suposed to be half decent for today which it obviously wasnt, and it is suposed to be nice for tommorow i'll admit i have spurts of speeding but thats the extent of it....

yeah he told me it has a different motor, he put in an S4 because the other one cratered on itself....

i ask alot of questions because i'm more then paranoid, i dont know much about rotaries yet there clearly different then piston engines, the fluid for the clutch was getting low, the exhaust was missing a nut where it bolted to the turbo and all of the car is in japanese ( Which makes things pretty freakin' hard ), wow do those sound like major problems too you?, because if anything that makes me look pretty damn paranoid over nothing.... looking after those things cured most of it's ailments, except for the sputtering....

steve drove the car how he drove it, it's in a different owners hands now and for one i take very good care of this car, alot of people can vouch for me....

and for the record, i've only raced it twice since owning it....

as for the sputtering, it seamed to go away after a good launch or running it a little hard.... not sure why.... but thats why i put that down and asked, i could guess at what the problem is but it comes and goes day by day....

by the way, in my first post when i said "speed" or "race" i was refering to the fact of moving a little quicker then normal, obviously.... you dont need to assume i drive like the anti-christ....

do you premix, is the OMP working, fuel filter good, just random questions heh, BTW i love your car.

Archangels

thanx man, i was thinking it could be the fuel filter, i'm getting one of those on monday ( $40! ) and when i install the walbro it comes with one for the tank....

if i do remember correctly the FC has 2 fuel filters, one in the engine bay and one in the tank with the pump....

the plugs are good, me and my dad pulled them, cleaned them a little bit and put them back, hmm....

oh and i'm not premixing, OMP seams good though....

#1 - Yes, there is a track in the city.. however, you have not yet taken the car down the track.. so where exactly are you "racing" ?

#2 - If you go back on some of your posts and re-read what you have posted concerning the problems with your car, most of your cures for it's ailments include smoking the tires, dropping the clutch at high revs, etc .. this isn't exactly "taking care of it perfectly fine"

#3 - The only thing japanese about the car is that you drive it on the wrong side.. aside from that, nothing is going to be different about the car from an N/A vehicle.. especially since it no longer has a jspec motor in it..

I will give you a couple hints though..

#1 - I suspect that your sputtering around is due to the F-con you have installed in your vehicle.. you also have the GCC.. It is probably set rich, which is causing your issue.. when you launch a little "harder" than usual, you are probably just getting rid of the excess fuel that's being dumped into your motor

#2 - Double check that your omp is actually working.. the person who installed the motor into your car gave me a call to ask me about parts interchangeability between s4-s5.. specifically he wanted to know if he could run the s5 front cover on the s4 block.. sure that's possible, however the s5 does use an electric omp, rather than the mechanical omp.. I am unsure as to which cover he finally decided on using.. what other s4/s5 combo parts did he decide to use to get the car back up and running and how are they workign with each other? who knows.. there WILL be some diffrences that if not address, will caus eyou issues down the road...

I have seen you on the road several times.. everytime, you've been driving like a clown.. since you already seem to know about the track, hopefully the weather will clear up for a friday and you can take your agressive driving out on the track instead of the streets..

Archangels

1- A large group went to medicine hat for "track day".... but i had spurts on deerfoot, yes i admit it....

2- Hey whatever worked worked.... my cures may have been expressed in an "over dramatic" way....

3- dude all the writing is in japanese, it's bloody hard to figure out whats what....

basically from what i understand it's the whole S4 block with all S5 externals....

hrm, i dont remember driving like a clown often, but yeah, would be nice to get the car to the track, take out some "agression"....

Well i fixed it for now, it only plays one song though: Dual Exhaust



I'm goign to buy a whole new setup eventually anyways **** it.

Archangels

thats AWESOME!...

hahaha....

it's like playing betoven in c minor, just different....

rx7_turbo2

Just a quick note. Archangels you drive a fairly high profile car (at least for those of us who notice RX's) Just keep that in mind when you talk about your driving habit's I've seen some "interesting" driving on your behalf, and on more than a couple occassions.

I would suspect the stumble is fuel related. Most likey rich, but since it's hard for someone not that experienced to tell the difference it may be a lean surge as well. I would recommend you either buy yourself a wideband, or get to a dyno with a wideband and find out what's going on. If you don't you may find this motor has the same fate as the one the previous owner ran.

Archangels

ahh i hope not, i believe it's a rich related stumble, if it was lean i would expect it to be more in the higher RPM range, it's not even making boost when it's stumbling, plus the odor of fuel is very potent after a stumble....

i should book myself in for some dyno time, i was hoping to get my injectors first though....

you've seen me drive too?, geez.... interesting.... and to think i've only been driving it a month and some....

rx7_turbo2

The problem is your playing a guessing game. A lean stumble can occur at any rpm. Now granted a lean stumble off boost isnt nearly as dangerous as a lean stumble on boost but still to be avoided. There's nothing saying it doesnt run lean for a bit and then go rich for a brief moment giving you that smell. Using your nose to smell rich or lean isnt exactly a very good way to tune a car. You really need some dyno time or a wideband in the car. We all run with a widebands in the car, and since I've installed it I'm not sure how I ever lived without it.

Like I said your car is highly visible to those who recognize it, and esspecially visible given the way it was being driven if you catch my drift

Archangels

sounds like i'm splurging for a wide band, i've glanced over at my AF guage and it's never hit lean with these surges and such....

yeah i realize my car stands out pretty well, i was only asking "how" i was driving it when you've seen me.... like what was i doing....

most of the time it sputters fire shoots from the exhaust, my friend informed me after he learned the hard way....

and it seams to get really bad, then not bad at all, then in the middle, and bounces back and forth, then sometimes it's not there at all....

i can only think of it possibly being fuel filter, TPS or FCON, everything else checks out ok....

Archangels

wow my car is really acting up now, i was driving on the highway taking a friend home when i downshifted and went to hit the gas and the car went absolutely no where, the revvs just died as if i put the car into neutral.... i coasted to a stop on the side of the highway and revved the car, it would revv if i gave it gas lightly, but if i gave it more, the revvs would just drop and when i let go decent sized fireballs came out my exhaust....

wtf is going on now, this is still the stupid sputtering issue....
