what will fix the jerking?

got gas filled up on May 1st, drove fine. on may
2nd i started the car she had some hesitation
but turned on, went to pull off she started
jerking and acting like it was going to cut off.
that afternoon i went out checked air filter (looks
good) and then i started her and the check
engine light was on. took the drive to advanced
auto (she stalled at the stoplight i turned it off
right back on and she went, put in neutral
whenever i had to stop). got the code p0011 so i
ordered the valves and on may 4th my brother
changed the camshaft solenoid valves (both)
checked the oil everything looks good. may 5th
got up turned the car on check engine lights off
and she drove to the store and back perfectly
fine. may 6th went out got the car started and
while in drive it jerks back and forth while
stuttering like it’s gonna cut off. help
