avalanche Posted April 29, 2007 Share Posted April 29, 2007 Hi I have a R33 gtst. My car no matter if its hot or cold will not idle. This is what it does car starts easy, revs to 1900 rpm,drops to 1500, pause, then to 1000 for a sec then dies. Stalls all the time. Runs perfect above 1500 rpm. I have a HKS Sq BOV. I have tried so far: Cleaning Acc valve and all that muck out of the back of the plenum Repacing fuel filter setting the TPS Turning Idle screw in and out with the TPS disconected ( For some reson the IDle does not change 1 bit weather i turn it in or out) Cleaning out the AFM Located where the Ecu idle screw should be, to find the isnt 1 on it checked for leaks what have i missed? Can someone help me out please! Link to comment https://www.sau.com.au/forums/topic/166540-r33-idle-problem-need-some-help/ Share on other sites More sharing options...
DRD-00F Posted April 30, 2007 Share Posted April 30, 2007 1. Go back to your stock bov 2. Get a plumb back bov 3. Get a tune your atmo bov will be releasing a lot of air into the atmosphere, yet your air flow comp will read it as being in the system, so the fuel will be added as if there is that amount of air in there... but its not... any of the 3 will fix this problem... normally an atmo bov wont cause it to completely die at idle, it does create idling and gear changing problems, but not normall this bad... which is why i said get a tune.. anyway, hope one of those fixes it for you Link to comment https://www.sau.com.au/forums/topic/166540-r33-idle-problem-need-some-help/#findComment-3084607 Share on other sites More sharing options...

DRD-00F Posted November 18, 2009 Share Posted November 18, 2009 You sorta can and you sorta can't. Do some research on Nistune. Are you running an after market plumb back BOV? What else is installed?

Craved Posted November 18, 2009 Share Posted November 18, 2009 please try an alternate stock ECU my old ECU was fried and i drove a car like this for 6 months lol - not fun looking like a tool revving your car at every set of lights. swap it out and see if you know someone with an stock ECU'd r33 Link to comment https://www.sau.com.au/forums/topic/166540-r33-idle-problem-need-some-help/#findComment-4943427 Share on other sites More sharing options...

Can someone help me out please! Make sure your fuel pump dropping resistor is plugged in. If any work has been done on the aerial recently it is possible the resistor plug has been unplugged. It is located in the passenger side rear cavity behind the wheel arch (where the jack is located). It is a rectangular silver item with a 2 pin plug.

What else is installed? i've also got a hdi GT spec hybrid intercooler, aftermarket coilpacks, a boost controller (only running 10 pound) and a HKS cat back exaughst system.. apart from that i'm stock.. i've checked for leaky hoses and i've tried a different ECU and i've replaced my air flow sensor..
