Hyundai Sonata 2002 idle at high RPM and accelerate 40-45 MPH

I have a Hyundai Sonata 2002 that I have replaced the idle air control still not fixed. It will accelerate to 40-45 mph on its own and idle to 2500-3000 rpm. I have to constantly hold the break while driving. Very dangerous! Can anyone suggest?

Look for a vacuum leak somewhere. This is the most common problem for a high idle.

I have a 2005 Hyundai sonata v6 bought used. mechanics cant figure it out and ive done all I can with no luck. car only goes 5-10 mph and wont go past 2k rpm

Is the accelerator blocked some kind of way? Maybe something is under the foot pedal. Also fuel flow like filter blockage or a bad pump.

Possibly but to find the fault have the fault codes read . It may be the accelerator position sensor . Don't waste money until you have the codes to point you in the right direction
