Wife's driving car and completely loses power when turning off highway. I know the PVC is bad but that part is due in today and easy change. Had towed to mechanic, couldn't get it to turn over but then unscrewed gas cap and started but has small clanking noise under cover in engine bay....??? Any thoughts on whats going on and whats also making clanking / knocking noise ...?

could be high pressure fuel pump, it is driven by a cam on the engine. You should check vitals with a diagnostic device to be sure your fuel rail pressure is good.
