I got a diagnostic run on my car, and it is MAF needing replacement and I can’t seem to locate it anywhere. My idle is rough and it bounces in between 500-700 RPMs. I know I have some misfires also; I broke a bolt in #4 coil bolt hole and it’s not snug, but it read the MAS. I need help, my make and model does not seem to have a MAF, I bought the larger round one that is supposed to hook into the hose.

This vehicle does not have a MAF sensor, it has a MAP sensor, here is the location. Check out the images (below). Let us know if you need anything else.
