Default 1999 mazda 626 accerlating problem

So one day I'm driving my car perfectly fine, nothing at all seems to be off. The next day it has this noticeable acceleration lag like the power seems to be weakened. Along with that it shakes the steering wheel, has an inconsistent noise when accelerating but it doesn't happen all the time. When idling in D the rpm's bounce not drastically but its definitely noticeable. I know most people are going to say get the codes, and see a mech. I tried to get codes but it wouldn't read due to electrical problems. Im bringing it to my mech in a few days since my paycheck is late. I'm currently not driving it so I hope to not worsen it.
