P0010 Intake Camshaft Position (CMP) Actuator Solenoid Control Circuit ECM
P0011 Intake Camshaft Position (CMP) System Performance ECM
P0102 Mass Air Flow (MAF) Sensor Circuit Low Frequency ECM, PCM

You're gonna wanna replace the intake cam variable valve timing solenoid and the MAF sensor.

ACDELCO Part # 15813321
DORMAN Part # 917215

 

Not messing with the MAF... yet.

I believe the problem is gonna be the actuator solenoid, and gonna do exhaust as well since they are beside each other. Gonna use the Dorman brand for both. Ordered them online should be here in a few days.

From what I read, they tend to go out around 70-80k and i guess im lucky mine lasted until 122k.

 

and its back...

I noticed the plug gaps were a little larger than they should of been, but fixing that didnt help.
Im about to try new plugs and new fuel filter to see if that makes any difference.

It likes to do it more often when the a/c is on...

Changed the plugs and the fuel filter.... still doing it.
I guess changing the MAF is next.

CEL has been off since I changed the cam actuator solenoid.

 

So I didnt change MAF, but I think a dirty maf has been the problem.
and the maf getting dirty seems to be because the air filter is a pain to put in with the way the housing hinges open and closed. It was causing the rubber edge of the filter to get pinched and Im guessing that over time it got the maf element dirty.

In other news.... the fuel pump is now whining and is probably going to die soon.
