car must be in transmission DRIVE selected? right?
and foot off gas pedal (accelerator)_ rpm goes to 2000 or up to 6000 rpm . and or
so driving foot off the pedal and RPM goes too high
or in drive, I step on the throttle (gas) and RPM shoots way high
and Never leaves 1st gear. that is transmission failures.
in DRIVE.
if rpm also goes that high right foot doing nothing and in park
that is engine idle control's failing.

in what gear? PRNDL (choices)
right foot doing what?
and what SPEED is too slow 20 or 85mph? or?

Check your throttle cable from pedal to engine,may have came loose or something has broke.Make sure floor mats isn't catching at pedal,I am a 350 fan.love to have one.Have a 85 Nissan 720 4x4 with Weber.
There is another sensor mounted to the gas pedal. It has to communicate with the throttle body assembly. If the correlation is not correct between the two, the problem will persist. The throttle body assembly is usually the most common of the two, however the accelerator position sensor still gives problems.
If its been without the line for over a year, I Highly doubt it. Look into IAC valve. Most are installed with 2 screws, easy to adjust. Idle Air Control Valve. Look that up, for a start.
If it is an auto then it is possible it is idling to high and the trans is still engaged despite you foot being off the peddle. Try lowering the idol speed as a first resort.
the gearbox is a "fuzzy logic"system.gearchange depends on accelerator pedal position/revs/load.if you drive without depressing the gas peddle more than a third down you should find all gearchanges much smoother.(if you drive with gas peddle almost hard down all the time yhe car will hold gears longer...poss 4500 revs or more......
Look under the hood for a big vacuum leak. Usually a large hose on the intake manifold near the front pops off. A big vacuum leak can cause a high idle. Hope this helps.
the Brake pedal is a huge Pedal. Move your foot over.. Be less lazy in your foot placement. Its an 08 so i'm assuming fairly new to you.. Its gotta be different from what your used too. Sit up straight, slide your seat up..move your foot over, and drive. Sleeping is for Beds..
