Me & my husband bought a used 2003 Hyundai Santa Fe in Nov 2017. We first had a problem where the car didn’t want to start after getting gas. We had to replace the pcv valve and never had that problem again. We also change the fuel pump fuse. Now our car has this problem where sometimes after coming to a full stop and then pressing the gas pedal down the car will go, but it won’t pick up speed and go It goes real slow. It don’t do it all the time, just sometimes. The car also don’t like to let me put the gear shift in reverse sometimes and our temperature gage also stopped working. The engine light is on. It wasn’t on when we bought the car and it ran good at first. Now it seems it’s one problem after another with this car.

    Hello, a 2003 would be "OBD II", this means that the on-board computer not only controls, but can post codes for problems with a lot of the functions. You need to first plug in an OBD II code reader, these are common now-a-days and you most likely know someone who owns one, they can be purchased at any parts store for under $50.00, and many parts stores, like Autozone and others will read the codes for you for free. Once armed with these trouble codes go online and look up the code to see what it means. Then search for detailed diagnostics to test the circuits or parts. The check engine light is an indicator that the computer has trouble codes for you. The gear shift not going in reverse could be the result of a misaligned selector position switch, or a more serious problem with the transmission, this needs to be checked out by a reputable mechanic. The temp gauge is likely a sensor or wire going to the sensor, something you could check out and fix yourself. Good luck and let us know how it goes.
