yes this feels like how my car is running, but will this cause low compression like i did?

Very possible, my car ran like crap, bad idle, bad gas mileage too. Not saying this could be your problem but a valve adjustment is simple enought to look into. I had 80K miles since the last one, so the honda recommended 100K is too long.
