I have a latest model Coupe/Tiburon SE 1.6 which has a rather annoying problem with regard to the engine revs. When decelerating under engine load (not braking) the car tugs incessantly and sometimes just carries on going as if it is driving itself. When you stop at a junction the engine revs rise on their own towards the red line. The only way to stop it is to floor the throttle which brings it back to idle. The car is fully serviced and has never produced a fault code when interrogated by the dealer. I have asked two different Hyundai dealers to look into the problem and neither seem interested once the readout has shown no faults. I asked an independant dealer to look at it and he admitted faults like this do not show up on the engine management system and he thought the problem probably lay within the engine management system itself, he also thought the problem was dangerous! I found on the net another post similar to this but on the previous model, it had received no replies (posted in 2002) but it did say the throttle sensor had been changed and had not cured the problem. Does anyone have any ideas?
