Ok, so I took my belt off to check the water pump and found out it is bad. Put it all back together only to find out I have 2 codes.

P0106 and P1101

To be honest, it's my wife's car and I can't say with 100% certainty that the light was not on before.

I did notice that it has a rough idle and at times seems like it wants to stall out.

Is the P0106 PCV/Valve cover issue? Is that causing the P1101?

We already have an appointment at the dealer for the water pump so I figure I will let them look into this as well. Just wondering what I might be getting into here.

Could be the valve cover. Usually throws a P0171 as well. Is the valve at the top right of the VC hissing?
Thanks for the tip. Sure enough, hissing from the valve cover. The round area at the top for anyone who wants to know exactly where. (See Pic) Auto part Vehicle Car Family car City car


Just for comparison, my son also has a Cruze so I had his running and other than the injectors clicking, his is quiet where mine makes a hiss, you can actually feel it when you put your finger over it.

I guess in a way I am lucky that the water pump and this went out at the same time. I can at least kill 2 birds with 1 stone at the dealer tomorrow. I am just under 50k so warranty is still good for powertrain.
