Isuzu Trooper 2002, rough idle

Whenever my trooper is in idle, like say a stop light the engine shudders like it's about to kill. While on the freeway it has a hard time switching gears as well as some shuddering and a high pitch squeal. Is it the transmission or an O2 sensor, a fuel injector or a bad vacuum pump? I can't put my finger on it.

Do you
have the same problem?

Check the EGR valve if its closing properly and also the idle air control valve clean it and see what happens
