I change to fully synthetic oil 05W-30, change the air filter and cleaned the throttle body.

Your problem is a leak in the cpi pletium most likely the pressure line has a leak
had same problem with mine $45.00 PRESSURE LINE KIT AND $15.00 GASKET FOR PLETIUM and 2 hours labor problem sovled.
You can remove vortec cover and remove air regulator to look inside pletium. I had gas vapor on driver side . that is where fuel lines are. fuel regulator is on passenger side. turn key on and look in hole and see where fuel is spraying. taking pletium off you can again turn key on and make sure where fuel is coming from.

do you have any check engine lights on? If you do, that is the first thing I would have checked. It does sound like plugged EGR, vacuum leak, or bad TPS
SOURCE: when slowing down & stopping 2005 Mazda tribute sputters and dies
Sounds like it could possibly be a vaccume problem, the computer sees that the vaccume has a low pressure and thus fludding the engine, or visa versa, it's seeing too high of a pressure and cutting the fuel comsumption to a minumum enough to make the engine sputter and die.. Does this happen when the cars in Netural or Reverse or Park? Just Drive?

sensors on the pedal?? not sure what you mean by paddel though never heard of this term before
Testimonial: "03 Envoy:My reduced engine power keeps happening. My car goes 20 mph. Changed throttle body, pedal, wiring. Need new thermostat. Car not heating up."

You never replace anything, on a Wishing,Hoping,Pushing,Poking,diagnostic approach
You learn the vehicles Systems,Test,then Replace,if you have a failed component.
Work on the Misfire Issues.
Then you lean O2 Codes will go away.
Not a the plugs.
Think lean---Vacuum leaks,EGR Valve leak,EVAP System leaks,anything with a hose that lets air into the intake system.
Exhaust System leaks,near sensors
