So I have a 2013 veloster turbo and all of a sudden on an on ramp I noticed power was cutting in and out. Almost like it was accelerating and going into a limp mode for half a second and accelerating again. The car was warm and only has 90,000 km on it. I turned the car on again the morning after thinking it was just a one time thing but then it was happening again. Every time i accelerated over 25% throttle it would cut in and out. The car idles fine and drives normally with light acceleration so I’m not sure what the issue is. I unplugged the battery to reset the ecu and tried again and this time the car would just cut out right away and the check engine light was flashing but then turned off after a couple of seconds. A week ago I had a tune up done to it at the dealership. New spark plugs were put in so maybe that has something to do with it. This has never happened before so I’m just trying to see what the cause could be. If anyone could help that would be much appreciated!
