I have a 2004 Nissan 350z with a 6speed manual transmission. It has 34k miles on it and I recently had to replace the Clutch/Flywheel. (Purchased the car with 32k miles on it). I put a JWT Clutch/Flywheel package in it as well as a Wilwood clutch master cylinder.

The problem is. The engine light came on, and won't go away. The codes I have are as followed.

P0021: Camshaft position actuator A - Bank 2 Over Advanced.
P0011: Camshaft position actuator A - Bank 1 Over Advanced.

I cleared the codes hoping they would go away (Mechanics ace in the hole -.-) And not 20 minutes later they came back. So I told myself I'd wait 500 mile, let everything break in, and then change the oil, clear them again, then see what happened. So I did. And the engine light came back with the two previous codes but also a random cylinder misfire code.

Could someone please give me some productive input?

 

Don't know what to really tell you... I've got the JWT Clutch/Flywheel combo on my modded 350Z Track Model, 491 hp and don't have a problem. You might check with a with a good car shop in your area that mods cars like ours. They could probably give you some advice, also don't do any unnecessary driving till you get it checked out. It might not be anything serious, but again don't really know and don't want to chance it. An ounce of prevention is worth a ton of relief. Good Luck.
