I recently swapped an s13 blacktop into my 97. After fixing my faulty MAF wiring(doh) the car is running ok. However the idle fluxuates from 1100-900RPM while sitting, if i rev the motor high and let off, the idle will drop to 300-400 and come back up. When im driving the car it stalls CONSTANTLY. If I let the idle fall to low it will just die.

Also i've read somewhere a faulty coolant temp sensor giving incorrect readsing could screw with your idle. I didn't swap the KA sensor with the SR sensor since my friend sort of broke it. Could this be causing my problem?

Good luck with everyting! Post some pics up. This Winter ill be working on mine. Hope everything goes well.

that sounds a lot like what my car was doing. i had a bad mafs and i swapped coolant temp sensors just for fun. try turning up the idle a bit too. i also have safc and boosting the fuel helped a bunch. good luck.

booooooost leak. my god damn BOV was leaking like woah, i slapped in a solid pipe and the car runs MINT. only problem is i dont want to boost till I get a new BOV cause im afraid ill fuck up the turbo, i heard running a little boost without a BOV will be OK. I have TONS of pictures I will be posting soon. Anyone selling a HKS BOV =]

97SilviaRB · 10-16-2004, 04:26 PM

Get a BOV asap dude.

statik · 10-16-2004, 05:00 PM

i know! im ordering one tomorrow, i need to drive it to work so i just wont boost i guess, not much i can do right now =\

TokyoNights · 10-16-2004, 05:24 PM

You NEED a ka temp sensor if you want your gauge to read properly. Also its safe to run no bov as long as you dont boost over 6psi.

Im aware of that, as I said my friend broke mine so I have to wait to get one on monday. Ill just try to avoid boosting as much as possible heh, hopefully should have a new BOV by middle of next week...

i have no idea what kind of hot pipe your using but maybe you could use a DSM BOV or a supra one or somthing from a junkyard unless your getting your BOV soon...

kazuo · 10-17-2004, 12:13 AM

DSM BOVs are junk... my friend had to crush his just so it would hold 7psi, and I think it was still leaking.

bomb-ass BOVs yo.
