master warning light, check engine light, and brake/abs light

I had replaced my spark plugs a day before my check engine light came on, the day the check engine light came on I also got an oil change because I was due for it.
So it started off with a check engine light reading code p0171, 3 days later my master warning light comes on as I am driving, and lose power of the car. It gave me a hard time shutting it off, and turning it back on, but was able to. upon turning the car back on I tried hitting the gas, there was a delayed response to hitting the gas, no power came from the car, but the engine revved loud for a few seconds, the spedometer read blank. I turned the car off and on again, the same lights were on, and same issues happened except now the brake light/abs light was on too. Still no power to gas, restarted it one more time, all the same lights and issues stayed.

anyone ever experience something like this?
I'm pretty stumped and scared it's either not fixable or way beyond what I can afford to fix.
Hoping to get it towed to a shop tomorrow

 

no anti seize, I used iridium spark plugs from auto zone.

it sucks because the mechanic that usually let's me use his shop to work on my car is an hour away from where it broke down, and I can only imagine how much that would cost in towing.
But my mechanic did suggest against cleaning the throttle body because it's electric, not sure if that's a thing or not.
I'm wondering if I cracked a spark plug somehow.
hoping it's something very simple.
