mite be the icv (located near the rev cable) that needs cleaning i had same problem idling around 400 and sometimes cutting out a carb cleaner will clean it
At 35mph it runs rough. Also when idling it will quit running, sometimes. Does that sound like I need new spark plugs? How many miles are new plugs & wires good for?
If your check engine light is blinking that means an ignition misfire has been detected
Rough idling is whenever the vehicle's motor "misses" or does not fire causing an imbalance and a loss of rotation reducing the motor's power and causing excessive shaking.

You dont you replace the timing control module

I would suggest a new set of plug wires.
