My engine check light comes on when driving, then after some days goes off when I start the engine, I just changed the thermostat because I did not get heat and the temperature gauge was working bad, my both problems are solved now but engine light comes and goes

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on.
