hey i have an 05 g coupe with 90k. a while ago i had my check engine come on, ran a diagnostic and said something with my camshaft and crankshaft sensor. so i changed all three of the sensors and it went away for a solid 1200miles. and check engine came back again for the same reason. so i did the sensors again thinking the sensors were bad. 500 miles later same thing check engine popped up and i am fn p.o. called my guy recommended i do a fluid flush and see if the problem goes away. anybody had this happen before or any insight on it? thanks in advance
