Question Runs rough - misses - poor fuel mileage

1995 PSD
152K
Stock w/ automatic

Runs rough at idle
Seems to have a miss
Poor fuel mileage

Autozone engine tester shows no codes
Check engine light does not come on

This just started happening about a week ago

I replaced the valve cover gaskets on both sides
Did not notice loose injector connection
I cleaned the dirty fuel regulator screen
I changed the fuel filter
I ran Stanadyne premium fuel treatment a 3x dose for past 400 miles

I plan to clean the exhaust orifice tube tomorrow

Anything else that could cause these symptoms ?

Before I start looking at an injector problem,
what else should I do ?



Thanks
