Sr20 running horrible help!!

[89JDM240sx]

Yes Sir you sure can...

[boris13]

UPDATE!!!!!!!!

I love this forum for all the help i received THANKS ok i shit my self over thinking again i went to my 240 and was tripping because of the missing coolant but i turned the car on and let it idle for a good 5-6min and it was idleing ok kinda wanted to die and kinda didnt it would sputter and want to die but i would keep it alive by giving it some gas i looked under the car and took notice that i was leaking coolant

the reason i had shit my self was because i was researching about cracked blocks and what not and that if its cracked i would be loosing coolant and thats when i shit my self but my dumb ass had a hose that was leaking the coolant so i re tightend the clamp down and it wasnt leaking no more so i decided to take her out for a spin around my block again this time trying to see if it would smoke up like last time and see how it would blow off after all the re doing of the clamps vacuums and what not and also to check if it would over heat on me so i take it around the block put it under boost and now i have flutter dump !!!

well its still not good but its better than what it was and also i wanted to see if it would smoke up like last time but it didnt smoke up at all now for the issue of it not staying on im not sure if i have to tighten my throttle cable a little bit or if i could still have a vacuum leak some where any input would be wonderful all the help you guys gave me is working slowly but surely i cant thank you guys enough!!!

Nice to hear the progress! Is your BOV opening?

[boris13]

well while its idleing and i rev it no it only blows off while im actually driving the car so i cant tell if it is infact opening right i took it off and pushed it with my hand to se how hard it is to open and its not that hard to open but i dont think it could be a factor as to why its not idling right and blowing off right can it??

Did you mess with your idle screw?

[boris13]

no i havent where is it located at? should i mess with it?

[89JDM240sx]

Where does the car idle at? Its located on the intake manifold

[boris13]

I don't know the tach I have on it is still the SOHC ka tach so it doesn't read rpms I'm going to get a DOHC tach do I can see what it idles at but I'm not sure as of right now but my boost gauge reads -10 then starts dropping to -5 an some times -3 then dies after it hits -3

[Nicelyphe]

You got the BOV running off the lower left nipple again?

[89JDM240sx]

Your Vac is supposed to read -20... Is it possible for you to take a pic of your bay and post it up?

[89JDM240sx]

Also check your manifold for hairline crack and such

He has some up on Page two I believe it was. I also gave him pictures of mine which idles at -20, but he said when he did it the way mine are his car wouldnt even idle so he changed them back . Maybe IACV is bad.

No I got the BOV running on the top nipple of it and from there it runs to the top right nipple on the throttle body

I got the top left nipple running to my FPR and T'd off to my boost guage

The bottom left nipple on the throttle body is running to my waist gate

Yea I took some pictures and posted them up I believe on page 2 the only time it reads -20 is when I rev it it will drop to -20 and go back to -10 at idle please be advised that I'm running stock tune stock everything besides the 255 walboro fuel pump and 300zx TT fuel filter (if that's even upgrading anything at all)

Yea I'm running same setup, walbro, z32 filter, fmic, and exhaust, stock everything else. You try spraying carb cleaner/starting fluid around vacuum hoses in search for a vacuum leak?

Hmmm no I havent yet what would be the response of it if I spray it with carb cleaner/starting fluid.?

[Nicelyphe]

Idle change, and depending, you can usually see it suck it in.

That line going into the manifold heat shield is that a O2 sensor?? The wrong one would cause the car to break up

[boris13]

No I don't think it's the O2 sensor because I believe it's behind the turbo I'll take a picture and post it it's connected across the valve I believe it has a white wire a red and black one I'm not sure I'll post a pic I'm not entirely sure about that tho

[boris13]

Ok I chekes the ecu for codes and it gave me code 12 when I messed with the maf

[Nicelyphe]

Get to try your buddys SR MAF?

[boris13]

K I'll try to see if he can lend it to me today if not imma have to wait till tomorrow

[Nicelyphe]

What ECU # are you running on that?

[boris13]

I have a #62 on it right now I also have a #63 sitting on the passenger side too

[boris13]

UPDATE!!!!!:O

so i went my local orileys and i bought some starting fluid!!! i sprayed all the cuplings and vacuums hoses and waited to hear for any idle change but i didnt hear anything so i spray the air filter and the idle kicks up and she idles beautiful and the boost gauge was reasing -20!!! i waited to see how long it would take to start dieing but it didnt.. so i take it around the block and i open her up she still flutters and acts like if she wants to stall out and die so i take it home and reverse it on to my drive way but then she stoped acting like she wanted to die..

i take her for another spin around the block and i can feel her hesitating and i would give it gas but i wouldnt respond for a second and the she started responding as if fuel wasnt getting through to her?? im not 100% sure on that but thats what it seemed like i put her on the drive way and she wanted to die i gave it a little gas and it started idleing fine i took a video on it on my drive way when i finished driving it after she was acting up but she wouldnt want to die or act up infront of the camera (liddo bitch)!!!

any way here it is.. S13 240sx SR20DET - YouTube

Have you checked the timing? Take a picture of the CAS.

No i havent checked the timing on it I have no idea how to and the CAS?? like you want me to take it off and take a picture or the inside?

[89JDM240sx]

That's the only other thing I could think of is timing and try switching out the plugs

[boris13]

mk ill try tomorrow im going to have an sr20 friend come over so i can try his MAF and if that doesnt help at all im going to take my CAS off and change the spark plugs along with the oil and sea foam the bitch and ill be damned if she still gives me some shit!!!
