2007 Chevy Malibu: traction control service light came..gears

I have a 2007 Chevy...
I have a 2007 Chevy Malibu and the other day the traction control service light came on and now it is shifting hard when going into drive and the first few gears. My husband cleaned the mass air flow sensor with the sensor cleaner and replaced it after it was completely dry and he also checked the voltage on the map sensor and everything seems to be at the right voltage. Can you help me figure out what is wrong??

Hello.
Welcome to Just Answer.

To begin, is the check engine light on?
Any other symptoms?
Is the speedometer working correctly?

Thank you,
Bernie

yes the check engine light is on and just today when we started the car it was idling funny but other than that the speedometer is working fine.
Hello Sheena.

Thank you for your reply.
So sorry about the delay.

I see your husband went to the mass air sensor. Was there a reason for this?
Did you get the code that turned on the check engine light?

Thank you,
Bernie

He works at autozone so he put the car on the tester and it gave him several codes and they were reading the map sensor and the mass air flow sensor plus some codes that were around the fuel pump area. My husband has been looking around and he read that the sensor should not be dirty cause it could cause issues so he decided to clean it and see if it helped at all but nothing changed.
Hello Sheena.

Do you have the specific codes that were gathered?
If you can supply me with them I may be able to piece together the puzzle for you.

Thank you.

Evaporative Emission (EVAP) Purge Solenoid Control Circuit

While I put the rest of this together, check the under hood fuse marked Emission 1, Fuse #6-10 amp. It may be blown.

Thank you,
Bernie

Hello again.

Here is what I suspect has happened.
That fuse has blown or it is not being supplied with power.
If the fuse has blown, one of the circuits that the code has set on has a short circuit.
Replacing the fuse will most likely result in the fuse blowing again,
Each one of these items will need to be checked until the short is located.

I'd suspect the canister purge solenoid and the oxygen sensors first.
