Hi I have a 2006 hyundai tiburon gt v6 and lately have been having trouble, when im in nuetral my cars rpm's starts to rise for no reason or stay at a certain rpm when im driving and dont even have my foot on the gas? Also my car sometimes bucks and hesitates I guess when driving at high and low speeds, ive changed the throttle position sensor to see if it helped and it still happen somewhat, so please if you could help me that would be greatly appreciated!

Hi martincos,

Thank you for the donation.

Were any trouble codes retrieved?

Do you have any coolant losses issues?

Yes one trouble code p0118 and I actually have been monitoring my coolant and after filling it up noticed that it was down below the low line in just a week, does this have any affect on the rpm's rising when im in park or nuetral, or the bucking of the vehicle when im driving?

P0118 is a fault with the Engine Coolant Temperature sensor and it can cause the the symptoms.

There is coolant leakages in the system and you need to locate and rectify the problem. If visual inspection does not reveal anything, a leak down/pressure test would be required to locate the source of the leak.

When coolant level is correct, and problem does not occur, then rectifying the leak should solve the problem. If it occurs most of the time, even after topping up the coolant, then you would have to diagnose and tectify the code.
