Unhappy Engine light on, hard shifting! Code p0014, p1104, p1174

Hi everyone, im really having trouble with my 2007 pontiac G6. Awhile back my check engine light came on, nothing really change an occasional hard shift here and there. Engine light would sometimes go off and it wouldnt shift hard. Now... its constantly on and it constantly shifts hard. I had it read on a computer at advanced auto parts. It gave me a p0014 reading, so i changed my crankshaft sensor. Didnt fix the problem. So i finally got a diag on it at VIP. They are now saying (with the same p0014 code) that i need a exhaust camshaft position sensor/possible oil condition. Plus i have a code p1104 possible injection problems and a p1174 secondary misfire but next to that it says "not at this time" Im very confused on what to do. Ive read alot of posts saying that other people had this same problem, got it fixed and nothing changed! I dont want to waste my money if this really isnt the issue! Please help

It has 105,000 Miles on it (Over Warranty!)

p0014 is Camshaft Position "B" - Timing Over-Advanced
or System Performance (Bank 1). It sounds like the VVT Solenoid of the cam (don't know for sure which one) has gone bad OR the camshaft position sensor could be bad.. I don't know why you would replace the Crankshaft sensor. but in doing so you need to re-learn the crank sensor angle. You need a computer or have the dealer do it.
p1104 is MAF Ground Malfunction that with the p1174 (a/f imbalance) so it sounds like you have a problem with the MAF sensor, bad sensor can result in A/F issues.

I would try checking your MAF sensor, make sure the plug and pins are all clean and straight and making contact. Maybe try cleaning the MAF sensor with some MAF sensor cleaner. It may need to be replaced. But I can't be 100% sure on that.

Typically, replacing the exhaust CMP actuator solenoid (don't confuse it with the CMP actuator--they are two different parts) resolves this. It is covered under the powertrain warranty so it's too bad you are just OOW. This has been covered in several threads so I would ask you to search on "P0014" first & then come back with any additional questions.

Is not applicable to your car so that is a bad code #.

Fixing the P0014 may resolve this code.
