i have this weird problem in my RB25 vl....at exactly the same spot of road, at exactly the same time, about 5min into my trip to work it happens everyday without fail. it goes into this closed loop idle of reving high then low, high then low...it gets so bad i have to pull over otherwise it will eventually stall...after about 3mins of this it comes good again, and it wont happen at any other time of the day other then in the morning travelling to work at the same spot. ie i go out to lunch and travel roughly the same distance and it doesn't do it. so i guess it must be a temperature dependent problem but what the hell?? ......weird thing is that i had idling issues when the rb30et was in it and thought i would get rid of it by installing a differnt engine but NO! ...just after some thoughts from you skyline ppl, ive posted this topic in calaisturbo forum aswell.
