Car acts like it's out of gas / won't go above 10 mph
I have a 2006 Hyundai Sonata, 3.3L V6. When I start the car the engine light comes on. It
won't move out of first gear it seems. It won't go above 10 mph. Maybe it'll go up to 15 or
20. I can feel the car go into 2nd gear, but it doesn't go faster. When I apply the brake it
shakes and sputters. It almost acts like it's out of gas, but it's not. I had this problem a
few weeks ago and then it went away for a while, now it's back. Also, when it does go
away, it will ride normal when I first get in it. If I stop and park somewhere, come back
out and start the car again, all of sudden it starts doing this. Any ideas?
