Hello, my engine is a 3lt. Engine misses. Engine light is on. Code test indicates camshaft sensor. Replaced sensor. Engine ran smooth for a couple of miles then engine light came on and engine missed again. Rechecked, same code , camshaft sensor, replaced again. Same result, ran smooth for couple of miles then light on again and missfire. Thanks for your help.
