R33 Idle Cutting Out Issue

[rollin_on_18_strong]

Hi all,

got a late R33, idles fine for about 30 secs then cuts out, all sensors except CTS have been replaced and set as per manual. Even bumping the revs up to over 1000, it will still stumble adn cut out after a certain period of time. It seems to me like a lack of fuel, but then it tuns fine on the road so that doesnt make snse

I know this sounds a bit vague but im hoping someone else has experienced this.

Thanks in advance

tried swapping in another idle control valve?

[rollin_on_18_strong]

Yeah tried that Pete

[Amec]

can you list EVERYTHING you have tried so far, so we are not suggesting something you have already tried?

I know you have said you have replaced every sensor, but "every" doesnt always mean "every".

[rollin_on_18_strong]

TPS,MAF, IACV , O2,CAS.

No BOV or aftermarket gear installed

Cheers

I just noticed "except CTS". I had a problem on an S13 that wouldnt run, replaced CTS and all fixed.

cutting out do you mean missfire? or the car stalls completely? misfire when car is cold and idling could be fouled plugs and/or failing coilpacks. Problem would show up more with advanced timing until car is warm... could be a possibility?

doesnt miss at all, just stalls out.

These late cars are a bit different for me.
