SES And Turn Signal Lights

Q. I have a 1994 Pontiac Grand Prix 6 cylinder automatic approximately 62,000 miles. The problems are as follows:
1. When the car is running but left in park for more than a minute, the service engine soon light comes on. Once the car is put in gear and moves the light goes out?

2. The turn signals do not blink and are solid green?

Please Advise?
Thanks

A. Probably two separate problems. You need to have it scanned for codes to see what's going on with the SES light. Probably an O2 sensor code. As for the turn signals, Sounds like a bad flasher which should be under the left side of the dash.
