Hi all,

A month ago I bought a Mazda Milly S 1995, it is the first time I own a Mazda, I like the car so far.
3 days ago the check engine light went on, I retrieved the codes today.

P0170 - Fuel Trim Bank 1
P0750 - Shift Solenoid A

I need some clues about what it could be the malfunctioning. If there is any veteran mazda owner or enthusiast who can give some clues I appreciate it.

Thanks.
