Rb25Det S2 Stalling Between 1000-2000Rpm

[markdem]

got this nasty little problem with my stagea stalling/hesitating between 1000-2000rpm. it does it whenever the hell it likes; under load, slow take off, cold or hot. and the dash doesnt display any warning lights, nor does it have any faults in the memory (i check by bridging the 2 connections on the diagnostic port). its also rather difficult to start and sometimes it wont start unless i use the accelerator. i dunno how to explain it any better so i took some shitty low quality video's on my phone

only mod is a cat back exhaust. the sensor after the cat has been cut. everything else is stock

any info is helpful. i got some pretty basic tools to test shit with like multimeters n shit so if it helps i can get some data for you guys.

thanks in advance tho dudes. you guys are always a massive help
