M35 cpm issues.....any ideas?

[Jbonez1252]

Hey all, I have an 06 M35 that recently did the whole stutter and choke on acceleration thing and then threw a bank 1 camshaft position sensor code, changed it...all good for a week, then it does it again and throws a bank 2 sensor code...change that, all good for a few then gives a P0021 and P0507...any ideas on what's going on here.....thanks for any input.

Welcome to the forum.

I'm not familiar with these codes, but have you had a chance to check the factory service manual found on this site?

There was a thread about sinilar symptoms recently, but there was no conclusion posted. You can't send member messages until you attain 10 posts, but it could be worth following up in the thread:

Before you do further replacements, I'd recommend cleaning your MAF sensor as well & or, checking for leaks in the intake tubes.
... and check your oil level.
