why is my car missing when i turn the air on or i am going up a hill on 2002 Chrysler PT Cruiser

seems to happen when i go up a hill and have to push on the gas

Asked by for the 2002 Chrysler PT Cruiser
Suspect pulg wire(s), possible coil pack. Time for a tune up!
Would this also cause it to die while driving ?
Not likely!.... You need a SCAN TEST...... the car does rather!
