Subaru Forester 2003...Anyone else have this problem-engine suddenly dies?
Check Engine light on response OBDII Code "PO519 SUBARU" pointed to faulty Idle Air Control Valve, Vacuum leak, Idle Control Valve harness open or shorted, Idle Control circuit connection as the possible solutions to this issue. Subaru Forester 2003. The engine suddenly and completely died as I turned a corner on a road out in the desert - no power, brakes, and super stiff to turn. Started up again immediately, but the check engine lights went on. Suddenly died and the check engine light came on. It was paved, not steep, but I had just driven over a 100 yards of gravel road. It happened again going downhill on an extreme grade, curvy mountain pass after I downshifted to second and pulled over at a cutout to let vehicles pass. The check engine light stayed on long enough to check the problem on his OBD (In the mountains far away from my home). The local mechanic said it was a complex layer of possible issues, even serpentine belt. But he was so unclear and it was very expensive and maybe it wouldn't correct the problem, he said. He did clean out the Idle control valve. The check engine light is off now most of the time. Does come on after I drive for long periods of time. I'm afraid this issue will happen again in a very dangerous circumstance, yet I am also not willing to believe a problem "maybe" could be fixed by a multitude of things. Thank you for your replies.
