ive had my safc II for about 8 months and my car ran great, no probs at all, then about 2 months ago, out of the blue, my car wouldnt idle at all.
sent my car back to the tune shop for a couple of days, after testing everything they could not fault anything. they had to adjust my fuel to +20% at ilde just to get it to idle then -20% off idle just so it was driveable....after a few more weeks my car went back to swap ecu's, no change, then we disconnected the safc and by-passed the wiring and car ran perfect.
any ideas on what when wrong with the safc and can they be repaired ?
