RB 25DET idle problems

[joseph0205]

Pretty much as the title says, I have a 97 R33 and the engine does not like to idle comfortably. On start up and warm up it revs itself to 1.5 to 2k which I assume is pretty standard but once it is warm it will drop right down to 300 to 500 (going by the tach it might be slightly higher but not much) and feels like it's a Cummins instead of an RB. The worst part is rolling up to a set of lights, if I don't engine brake the whole way it will stall and I have to blip the revs whenever I have the clutch in. Once it recovers it will idle, but will feel rough (usually around 700, slow enough that the aircon doesn't really work, also another problem I have with the car, the aircon won't be cold lower than 1.2 to 1.5k rpm, I assumed this was a part of the previous issue). The exhaust also smells quite fuely.

 

The car is pretty much stock apart from a front mount, BOV (which is set to full recirculation anyway) and a pod filter and always runs 98

 

I do plan on eventually putting a haltech or equivalent ecu once I find the funds but that could be years off so any help fixing this would be great,

 

Thanks in advance
