Hi All, I have a 2004 Hyundai Sonata 2.7 6 cyl with about 160K. I bought it used and all has been fine till yesterday. While driving home the throttle suddenly started to surge wildly. While holding the pedal down 1/2 way it will rev to 4-5K for a few seconds then drop all the way down to nearly 0 for a few seconds then repeat this sequence. I checked the code and had a TPS error No CEL, Replaced from Autozone, but still is doing this.I cannot drive past 30- 35 mph. CAN anyone HELP Me
