bilbo117 Posted January 31, 2006 Share Posted January 31, 2006 Hey guys... My car has had this problem for a while... After a nice hard boot (or a couple of them immediatley after each other ) my car starts to pop when going down in revs while in gear... if i clutch it, it sometimes dies completely from this. it comes good again after a minute or two but the harder i push the car the longer and worse the popping is. does anyone know wat this could be? its quiet loud with a straight through 3 inch exhaust... thx in advance, bill Link to comment https://www.sau.com.au/forums/topic/104041-r33-gts-t-wtf-is-wrong/ Share on other sites More sharing options...

Links Posted January 31, 2006 Share Posted January 31, 2006 Hey bilbo117.. This is the same as alot of people that are running stock cars with maybe just an exhaust.. After we discussed it with a couple of people in a thread we narrowed it down to car running overly rich and by giving it a boot your exhaust temps are rising massively especially around the turbo.. as you back off the throttle, excess fuel is dumped than ignited by the heat as it passes through the exhaust housing.. do a search..

fooey Posted February 4, 2006 Share Posted February 4, 2006 Yup, the pops are just backfires from (lots of) unburnt fuel... shouldn't cause any harm except for black exhausts and bad fuel economy!

Tommyk Posted February 5, 2006 Share Posted February 5, 2006 my popping seems to have gone away, since I have had the car retuned. Id say exhaust temp rises you back off, fuel goes out the back and ignites since your exhaust temps are around the 600+ degrees mark Link to comment https://www.sau.com.au/forums/topic/104041-r33-gts-t-wtf-is-wrong/#findComment-1924760 Share on other sites More sharing options...
lingeringsoul Posted February 10, 2006 Share Posted February 10, 2006 Im getting that problem these days, the car dies when I clutch in, which in turn gets rid of ANY power steering AND brakes..........scared the shit out me when the damn thing wouldn't turn and stop. must go get it tuned.

[200] Posted February 10, 2006 Share Posted February 10, 2006 sometimes an after markets bov that isnt plumbed back can cause this problem aswell, particularly if the car hasnt been retuned. Air that comes from a bov has previously been metered by the afm, if it is not plumbed back and you have no compensation, the engine will also run rich during the time shortly after the bov operates.I wouldnt be to concerned, my cas a constant flame thrower, cops sore it once, F#$k i was up that special creek with no paddle and a sinking boat that day !

MR R33 Posted February 11, 2006 Share Posted February 11, 2006 if the car dies when you put the clutch in, let the clutch backout in gear, and the motor will kick back in, its called a rolling start.
