Vehicle sputtering and missing likes its going to die at stops
I have a 2002 Elantra GLS, in the past 2 weeks the car if you stop at a redlight or to just sit and let it idle, it misses and acts almost as if its going to die just like it could be water in the gas or the plugs are fouling out. Could this mean its ready for a new fuel filter or new sparkplugs and wires? I changed the oil and added gas treatment but it still keeps doing it.

Sounds like it could possibly be a vaccume problem, the computer sees that the vaccume has a low pressure and thus fludding the engine, or visa versa, it's seeing too high of a pressure and cutting the fuel comsumption to a minumum enough to make the engine sputter and die.. Does this happen when the cars in Netural or Reverse or Park? Just Drive?
My 2000 Grand Cherokee had the same problem, without all the sputtering, it would just die approaching a stop. We could only keep it running by slightly pushing down on the gas petal when coming to a stop. I replaced the Throttle Position Sensor, but that didn't change anything. A new mechanic I found replaced the Idle Air Control Valve, and we've had no problems in a week.
my 2002 elantra gls sedan started blowing hot air and overheating and it turned out when i took it to the hyundai dealer it was my thermostat they replaced it and i was good to go.it happened at about 40,000 miles hope it works out for you
I had a similar problem.
At a cold start the rpm would come up normally then slowly drop then stall out. Car would stall at lights and stop signs. My mechanic after having for 3 days found a faulty cam sensor.
