Uneven running of engine

I have a 1996 ssangyong musso with a mersedes 3.2L engine,this car has a rough idle.It has a new mas sensor a new oxygen sensor,the throttle body has been cleaned ,and the engine has been tested for air leaks. When the engine is hot it settles down and can run normally but if switched off for 15 minutes and then started it returns to lumpy and uneven again. can anyone help

Where is oxy.sensor
Usually in the exhaust pipe near the engine.
They don't usually cause a rough idle, and the check engine light should be on if you have a faulty sensor.

1996 Galant runs rough until gas pedal pressed about quarter way down,then runs fine.Car is running lean.Not sure how to check if fuel pump is working correct,or maybe MAS?
You should have your TPS and EGR looked at as those cause rough idles...Other causes are bad idle air control valve, bad plugs, bad distributor cap & rotor, a bad wire, bad O2 sensor, etc...
