Whole scenario....Just had car return from shop conditioner

Customer Question

Whole scenario....Just had car return from shop for air conditioner replacement. Car drove home great, no problems this tuesday. Wednesday we took it out for a drive, ran great, no problems.
Friday, we got in turned it on, sounded rough. Able to drive it a block then died. Turns over, idles ok, until you accelerate and it coughs chokes and dies.
Came home, looked under the hood to discover 5 baby mice housed above the manifold. All wiring on the plugs and manifold look fine. Air filter was chewed by mice.
When it starts, it fine, and idles hard. Any acceleration to the throttle, and it couphs, chokes, makes a low muffled sound from the throttle. and dies. Mechanic is stunned. Throwing codes that make no sense...blowing lean, mifire codes (which its not), and module 2 error. This is a 2008 chevy cobalt.
Mechanic is wondering if the mice could have ruined the mass air flow sensor, if its th O2 sensor, throttle body or just the entire Power control module....we need expert advice

Expert:  Gary replied 4 months ago.

i am very curious on the code number set for the module 2 error

that is fine knowing the code numbers set will steer us to the problem area

Ok, I will respond when he gets back to me.
Expert:  Gary replied 4 months ago.

sure thing

Customer: replied 4 months ago.
He said there was no numerical codes. Module 2 not responding using live data on the diagnostic device. Unable to retrieve the code.
Customer: replied 4 months ago.
He wonders if its the MLF sensor that got plugged up by the mice
Expert:  Gary replied 4 months ago.

but you said it was throwing codes

what are the code numbers

if its throwing codes there should be code numbers

Customer: replied 4 months ago.
There are no numbers..but since last spoke.....weve now cleaned out the MAF and the throttle body. Sounds much better. Lots of Mice debis on the MIF. Now its throwing out Throttle body position sensor, and the inside dash says "low power" which correlates to the Throttle body positioning. TP sensor 1 and 2 error
Expert:  Gary replied 4 months ago.

usually with low power being lit up in the dash there is a throttle body issue itself causing this porblem

with no codes set and low power in the dash then either the MAF or the throttle body would need to be changed
