Minor Issues, Idle And Backfire R33 Gts-T

[chris_82]

Hi guys, just wanted to get some info or thoughts on my R33, its a series 2. Ive only had the car a few months and noticed its got an idle issue, this issue isnt full time, it mostly occurs when being driven for half hour or so (completely warmed up). When i stop at traffic lights or pull into my garage it has a slight hesitation if the accelerator is stabbed quickly., (to say i was creeping forward in traffic). Once it recovers the idle drops below 500rpm and struggles then goes back up to about 800-1000rpm and sometimes it even stalls. Ive also noticed there is a clicking noise when the accel pedal is pushed in when this is happening.

My other issue is a small backfire between gear change, 2nd to 3rd and 3rd to 4th. Its a slight pop but sometimes louder than others. It doesnt pop when on near to full boost or if completely off boost. Sort of mid range 0-3 PSI. Also is this backfiring doing any damage?

Mods of the car are-

3in cat back exh

Blitz SUS filter

Blitz BOV

Turbosmart T boost (8PSI)

Other than that its stock. I run Vortex 95 and 98 in it. Any help would be good.

It is 100% the blitz bov, needs to be plumbed back into the intake or removed and a standard one fitted (and plumbed back)

Yeah its a genuine Blitz bov with the aftermarket pipe. Im also still running the stock bov aswel, so 2 operating BOVs.

Lol at another bov thread.

How about you do a search for " bov stalling"

[chris_82]

Why does a bov interupt the idle ? wouldnt it be a full time issue if this is the case ?

See im confused now, because the first part of the post is perfectly matched to my car, only i have stock bov. When my car gets warm it will sometimes drop really low in revs, sometimes even stall with the very slightest of a touch on the accelerator. Not a problem at all when you take off normally as such, i mainly noticing it when parking or reversing etc, where its only very little throttle.

When i bought the car it used to basically miss or stall all the time when slowing down with the clutch in, but after cleaning the aac valve it is now only with slight throttle pushes..

Sorry for the hijack, but nothing came up in search and i didnt get around to my own thread.
