Motor stalled on highway, no issues beforehand. Wouldn't restart, pulled codes P0340 and P0345. Replaced camshaft sensors, reset computer, car started but sounded bad when started. Idles fine, press the accelerator and ticking sound comes from motor now. Towed to shop. Any ideas what I might be looking at here ? No new codes have come up. 2012 G37XS. Heard back from the shop. Rod ticking apparently. Gettting estimate for motr replacement
