My 2003 Tiburon GT V6 5spd has been intermittantly hestitating and missing while at a contant speed and even stalling out from time to time. Also, the engine revs high at 2000 rpm then back down to 1000...


have you changed your fuel filter in the last year or so, if not. do it. a plugged up fuel filter will cause a lot of issues also. it can cause stalls, hesitation and stumbling.

Engine will not rev above 3000 rpm


Inadequate fuel pressure, change the fuel filter first, make sure the car sits for at least two hours before replacing the fuel filter because these fuel lines are under high pressure during the time of operation. The pressure usually decreases over time in the lines but wear safety glasses just the same, I would recomend depressurizing the fuel system first, buy a Haynes repair manual for detailed procedure to be safe. If problem persists go to Auto Zone and ask them to check for trouble codes these codes if present may instuct you in detail to replace the MAF sensor or give you a code that must be looked up to find the problem.

It could be the filter. Has the fuel been changed after storage? I would also thing the Carburetor or the fuel injectors might need to be cleaned.
