I know this topic has been covered countless times, but after trawling through loads of threads, I can't seem to find one with the exact same problem as mine.
Basically, when I start the car and rev it, its fine. When I pull off its fine, until I try and giv it a bit of welly, then instead of revving like it should it just kinda goes 'BRRRRRRRRRRRRRR' like a burbling sort of sound. When I hold off the throttle it seems to go until I try to floor it again.
It also seems to get worse when the car warms up. It starts to burble and hold back with even less throttle. It boosts fine, but I don't think its over boosting because half the time the boost gauge isn't even reading half way. Plus after the car has warmed up it burbles a bit when I rev it in nuetral too.
Any ideas folks?
Oh yeah! I've run it through my laptop with Nissan Datascan software and checked the Datalog graphs, but tbh I don't really know what to look for.
Also, the car is fitted with NGK Iridium plugs, Magnecor leads, a Warlbro pump, plus the dizzy cap and rotor arm. All these parts are about a year to 18 months old, as I changed them all to cure a similar problem before.
