Ok... because I have a P0012 code which I changed the The two solenoids and the code is still there after I erased it.. idk if I need to replace the two camshaft sensors that***8217;s causing the code... also I have a P0300, P0301, and P0304 cylinder misfire and I ended up replacing all six coils and spark plugs and the codes are still there.. And on top of that there***8217;s that loud whistle the only happens after the car is running for awhile and I***8217;m guessing whenever it reaches to a certain temp it starts whistling. Idk if the valve cover or pcv are the ones that***8217;s causing this codes.
