Have a 2012 Buick Regal Ecotec 2.4 with 95K miles. Had engine light with PO340 code to replace camshaft position sensor. Was getting no drive-ability issues at the time, but replaced sensors.
After a few months, now getting hard starts when engine is hot. No issues starting when cold and no issues while driving. When the hard starts happen (long crank before starting), it's throwing the camshaft position sensor codes. I doubt that's it -- what are the odds that the CPS are bad again? ...and why only when hot?
All help appreciated! Thanks!
