Idle problems

Recommended Posts

Hi, I seem to be having lots of problems when the cars first started, if I leave the engine warming up it will start idling at 1k and then keep dropping til it nearly stalls. If you drive it, it runs a bit lumpy and when you get past 2k revs it just cuts out power, it may do this a couple times then just run fine. After driving for a while the revs seem to idle around 1100rpm. I've recently had my turbos rebuilt as we initially thought that the first turbo had stalled starving air into the engine, I've cleaned the icv, changed spark plugs and tried different coil packs and the problem keeps coming back. I'm guessing I need to buy a new idle control valve but just thought I'd check to see if anyone had any ideas. Thanks.
