this information just helps for anyone helping to know what your baseline maintenance is thus far.Shoot, I knew I was forgetting something. Plugs and wires replaced in the past year as well. o2 sensors are unknown. It's been a busy year and I took care of as much as I could after buying her.
my personal experiences with stumbling have been #1 throttle body #2 maf
it could be many things though....you just have rule things in/out as you go along
if the air/fuel information is off from what it is expecting then it's going to hiccup, the maf can cause all kinds of issue's if the reading wrong or if there is un-metered air getting in
hence a scanner that can read live data is very helpful
