1998 Plymouth Other

Engine problem
1998 Other Plymouth Models 4 cyl Front Wheel Drive Automatic 95000 miles

I have a 1998 Plymouth Neon DOHC 2 dr. It seems to be idling a little high ca. 1100 rpm. While in drive and stopped it seems to idle ok, until I release the brake and allow the car to roll forward, it begins to accelerate on its own, to about 2000 rpms. I recently let the car sit for a week or so and when I came back it idled very rough for about 3 minutes. The check engine light will come on for a few minutes then go off for a few days then back on for a few minutes. Haven't been able to check the code while the light is on.
