Listen bro, listen. (SR20 halp)

S13 SR.
Starts up fine.
Then idles like sort of okay for like maybe, I dont know, like 1 minute maybe. Not even. (Note the 3 "likes")
Then idles gets funky. Brass monkey. surging. Until it eventually kills itself. I can keep it running by holding the gas.then once motor gets to operating temp , I let off the gas it just dies. Doesnt try to idle or anything. Just ka-poot.
Breaks up bAaAd around 4.5k under no load. Like Im hitting limiter or something. POP POP POP.

You bros ask, I answer.
Ciao!

Almost posted this in "Off Topic" because I hate technical mumbo jumbo.

Is it running super rich?

That's what it sounds like to me. Could be wrong

It was. Put a different injector in because the O-ring thing was torn.
Exhaust smells fine now.Is that how you tell haha. I suck at cars.

check the idle air control valve. unplug it, adjust the screw, etc

Timing?

oh and for this:

"Breaks up bAaAd around 4.5k under no load. Like Im hitting limiter or something. POP POP POP."

sounds like a bad MAF

Yeah that sounds like a MAF problem.

I'd also say check the maf.

yea that's def maf, i think i have a stock SR maf. give me the model #/part # or w/e and i'll check after i get off of work. u can come by and pick it up

single cam maf's also work for this.

alright I'll try that.
Do you think that would correlate with the whole running like shit when warm?

Are you running any tuning at all? do you have a wideband? It could be a ignition problem.

Advice needed, not teenager carboy misdirected speculation.

We tried my maf, my coilpacks, ignitor, checked for any vacuum leaks, Ecu etc. Nothing changed. Tried my plugs and bam! Car runs. But it fouled them and wouldn't idle. No breaking up, just super rich. I'm using Ngk bkr7e, his car was originally using bk6r's... It ran and pulled hard with no problems except idle with my plugs, but anyone know why it could still be running so rich? Sorry for long rant of a post, but were out of ideas..

unbolt the fuel rail, but keep the injectors in it though. prime the car and see if the fuel is leaking out.

Didn't leak when primed. Also we swapped fpr's

aftermarket FPR by any chance? or stock?

i had a aftermarket one and it would flood my shit. threw it in the garbage went back to stock.

Stock ones... I'll try messing with the tps and see. That's the only thing we haven't tried.. And o2 sensors. But those don't do shit.

Thanks for helping Mike, Mr. Teo guy.

^^ ditto

Im always down for helping out if I can. But it's still not working. Messed with it a little today but didn't have much time, still need to try the tps. Anyone know if coolant temp sensor or iacv could cause such a richness??

tps generally fks with alota shit so check that out.

iacv would just fk with your idle

Went out and just messed with stuff. Tested my O2 connector with a test light in all three slots and none of them lit up. So my O2 sensor is getting no power? or is this normal? Id guess not...

that wont cause problems. o2 sensor pretty much does nothing. I never even had one on either of my SR's

Mine didnt have one either.
