so anybody fixed the idle problem, as I am having the same issue, sitting in traffic, even driving round the narrow english roads, at traffic lights does the same. The car looses power and feels like running without boost, but the gauge shows full boos on both turbos.

Full stock FD3S came form japan about 2 years ago.

Had it for 2 weeks now.

Changed plugs - NGK 2x7 and 2x8 , oil, oil filter.

 

Anybody???

my car sometimes very hard to start,after that when the engine is hot the idle went down into 600 rpm.. and also the car sometimes stall.. then my car always backfire in low N high rpm..

this problem came to my car last time when i boost from 2000rpm into 7500rpm in gear 3.. when boosting i hear crack sound and then the problem came.. before that my car just run perfectly..

did you read and try the things suggested in this thread? pretty much everything that controls the idle has been addressed in the thread just start checking things one by one. then after trying everything suggested post back with what you tried and what happened when you tried it. If you fixed it post back with what worked for you. if not post back any changes if any and we go from there.
