I have a 2004 Hyundai Sante Fe 2.7L 4-Wheel Drive. Every time I stop for gas, after I start up the car the engine will cut out 2-3 times. I cannot take off right away because its like the car has no power. I have to play with the gas pedal for a while before I can take off. (The engine is easy to start, but every time after I get gas and try to start, it cuts out 2-3 times.) It has been like this for 2-3 months. What could be wrong? The check engine light does NOT come on. The local garage did a scan test and there was no code, no nothing.
