Help!!!! Please!!!1

I've got a 94 Camry that once it gets warmed up starts sputtering and stalling out at lower rpms. I've just changed the fuel filter fuel pump plugs wires distributor and cap and cleaned the egr and it still idles rough and then eventually stall out. If i keep the rpms up at 2500-3000 it will stay running but anything lower than that it starts sputtering. The best way to describe the sputtering is almost like it feels if it were running out of gas or the engine was missing.

 

Clean the IAC valve.

Check the coolant temp sensor for computer, ETC.
