Recently went in pep boys to get my CEL checked and these are my code:

1405696 - Left engine mount solenoid
170240 - Boost pressure regulation control range not reached
2195712 - Performance malfunction in cooling system
3214080 - Low pressure fuel regulation

I'm sure this is gonna take a lot of time and money to fix, but was wondering if I could do all these fixes one at a time over the next few months without having to put the car in the shop for that long......any advice would be appreciated
