Question about 1997 Hyundai Sonata
The engine starts, but when pressing the gas pedal, the engine stops. It seems that there is a problem with the mix of fuel and air. May it be the automatic choke that wont release?if so, are there any fuses I can disconnect to disable it?
There is no automatic choke. The engine Power Control Module reads all of the signals from the various sensors throughout the engine & cooling system to determine the air/fuel ratio.
You'll need to make sure your tune-up isn't due, that your air filter is in good shape & not restricted , including something being drawn into the filter opening.
You may need to test the pressure of the Fuel Injection system with a set of gauges to determine if the fuel filter or fuel pump are restricting the fuel flow. Fuel filters can restrict the fuel flow if plugged from years of use & not being replaced on schedule.
It's a good idea confirm that the Catalytic Converter isn't restricted (or any other exhaust component).
Generally converters will cause engine overheating, seal leakage, and "rotten egg smell" as they are going bad. A plugged exhaust or converter can keep the engine from having power since the exhaust is not allowed to exit. Usually a small amount of fumes will get by the converter giving a small amount of exhaust even when it is bad.
Your car is OBD II compliant which means that if you have any check engine lights on, you can get it checked free usually at one of your local auto parts stores. They only have to plug in a handheld device below the dash to retrieve any trouble codes that your car has & it indicates what the problem area is. (This only works if you have any codes stored that triggered the "check engine light"., and you haven't disconnected the battery causing the codes to be erased.)
I hope that this will get you started in the right direction. There are so many variables when it comes to cars & the many things that are used to make them perform properly.
