if not first thing i would do is replace air filter.
next look at sprk plugs, look especially for spark plug tubes to be full of oil,if so replace valve cover gasket and replace spark plugs and wires.
Check fuel filter too.
if check engine light ,find what is the code and start working from code .Could be TPS sensor,etc.....

Your pressure washer sounds as if it has an air lock. You need to run your pressure washer, full blast, and aim it towards the sky until the sputtering stops. That should take care of this problem.
The 99 Blazer could be sluggish for several reasons. Check the air filter fuel pressure and EGR valve for a start.
