I do have a Mitsubishi Dion 2000 with a 4G94 GDI 2.0 L engine.
Cold start: no problem, but while driving in a traffic jam then engine idling is poor: rpm meter goes up and down and engine goes off and check engine light turns on. Engine will start immediately but i have to put pressure on gas pedal to prevent engine going off. Many times i did use injector cleaner, but i am sure that injectors are ok.
How can i let this problem be solved?
