25det Auto (r33 S2) Strains To Idle Sometimes

[qikstagea]

Has anyone else had this problem?

The above engine in my stagea has dramas keeping a solid idle when cruising slowly round carparks, idling at lights, etc. It NEVER turns off, but drops down enough that you can feel the power steering fall away, and the rmp needle drops below 500.

What would be doing this? car has had a babied 50,000k til i bought it and brought it over, and has now done 65,000, with cruisy driving. I figured it may be a vacuum leak at low revs, but was just hoping someone else had come across this drama and could give me an answer. note, its an auto, dunno if that makes a difference.

Car doesnt miss a beat under power, starts first time everytime after maybe .5seconds of the key at ignition.

I run pulp everytank, with a NOS injector cleaner/booster every 5 tanks or so.

thanks in advance to whichever guru answers this one!!!

I had similar issues with my auto R33 RB25DET.

I would rev it to maybe 2500RPM (not much because this would happen in carparks etc) and if I let off the accelerator pedal it would stall or come close to stalling (power steering dies, battery light comes on)

I noticed this happened until I fitted/tuned my SAFC2 and then these issues stopped so it definitely has something to do with the airflow reading.

I had a pod on mine too - not sure if this was the problem.

Try checking the Gearbox fluid lvl, if too much fluid is inside it will interfear with the operation of the valves inside
