Why else is my 17’ equinox stuttering

Started up my car she had a rough idle then calmed down, put her in drive and
the whole car started jerking. Got the check engine light on got it to auto zone
(stalled at a stop light once it turned right back on and drove, any time I had to
stop I just put her in neutral). When I got to auto zone the code was p0011. My
brother Replaced the camshaft solenoid intake outtake valves, check engine
light turned off got up ran to the store the next day all seemed fine, left the
house again started up just fine, put car in drive immediate jerking like a
bounce like the car couldnt breathe? I waited and put her in park and the idle
was normal nothing rough at all. No check engine light as of now.. facts: oil
change done end of February, oil level is good. This just started on May 2nd,
filled up the tank on the 1st, replaced the camshaft valves on the 4th. Now on
the 6th she’s still angry.
