Vehicle starts ok but may idle erratically. When driving at slow speed the tach shows erratic rpm. When you stop at a light or slow to take a turn engine may cycle from approx 800 rpm down to almost 0 on the tach and sometimes stalls. When in park and warm idle can also be very erratic.

Check your IAC module, change the fuel filter, plugs, and wires. Also clean out the throttle body and EGR ports, that should solve it and are all normal maitnance procedures.
