ROUGH ENGINE IDLE

1996 Saturn SW1

Engine Performance problem
1996 Saturn SW1 4 cyl Front Wheel Drive Automatic 236000 miles

Hi, I have a 1996 Saturn sw1 station wagon. When the car gets to a nice warm running temperature, the car vibrates and idles rough when stopped in drive. When I switch to neutral, it's better. Does anyone know what causes this or how to fix? Is my car just old? Please help! Thanks

Check and test the IACV, EGR/PCV valves and TPS sensor-
