hey, i have a 91 acura integra ls automatic, and for some strange reason my s3 is flashing only when after ive driven the car, then i come back to it 15 mins later and it wont start, so i have to let it sit for a bit then it will start, the s3 flashes 3 times to be exact, someone help! thanks

 

The s3 light blinking could be an indication of a problem with the transmission. Maybe a shift solenoid...

The no-start is probably un-realted to the transmossion issue. There should be a light on th ecu that will flash (short for ones and long for tens). See if you can determine the number it's flashing out and google the trouble codes to find out what they are. Post up what you find...
