Replace all what? You just said you replaced your battery and alternator.

Post your codes.

I only replaced the alternator and the serpentine belt and battery. So doing some research it says it could be engine control module or power control module. What do u think?

I presume you did the work yourself, otherwise it would be back in the shop, correct? So in doing this work yourself, you have access to tools and a multimeter, correct?

My stepdad has a garage and a lift and he fixes all of my cars. We have tools but what is the meter u speak of?

It's a meter for testing electrical stuff.

I think you should pick up an OBD2 dongle, get an app for your phone and post your codes. I'm not sure I will be able to help you out much beyond that. Maybe someone smarter than me will chime in. 6th gen forum is pretty dead most of the time, so I check in once in a while to see if there's anyone I might be able to help out.

Holy smokes, you replaced so many expensive parts but did not even read codes? Tell me that is not true.
Like User1 said, buy a cheap scanner and read codes. In today's cars you can do nothing with the electric without two things: OBDII scanner and multimeter. Google those terms.
