V9 STI Idle Control Problems
Hi Guys,
I started my 05 sti the other day when it didnt seem to be running properly. The revs were surging from 1200-2000rpm.
The engine management light then came on so had it plugged into a diagnostic machine that gave the code P0519 Idle Control System malfunction failsafe.
Can I assume that this is the problem or could it still be something else other than the idle air control valve? Air leak, MAF, etc?
The car is only a few months out of warranty and a new IACV is £375!
Has anyone experienced this before?
Cheers
