35968 miles and I get a check engine

Probably needs a new valve cover (PCV valve) if it's a 1.4L. Pop off the spark plug cover and listen for hissing @ the round disc on top right.

This is covered under 5/100K powertrain warranty.

Yeah I got a P0171 code at around 39K, most common problem is either a loose oil cap or a dipstick not pushed all the way in. Crankcase has to show around 19"/hg vacuum at idle. My problems was a leaky camshaft cover, was covered under the 5 year warranty. But only around a 40 buck part anyway with a new gasket and all new bolts.

I got the check engine 30 miles from the warranty end and p0171.
By the time I got home I was over 36k but I reset computer after checking and not feeling or seeing anything.
One week later back again then 3 days. I changed air filter tightened all connections and CRC cleaned the MAF
No visual or audible vacuum leaks. 36 thousand miles..Did they GM do this threw the ONSTAR...No seriously
any input greatly appreciated.
