I have a 2001 Lesabre Limited that is causing me some problems with it'* "warm" idle.

When I start the car in the morning, everything purrs along great. After driving the car for awhile....engine has warmed up....restarting the car say after getting gas, etc. is weird!

When I restart the "warm" car, it idles rough ~600 rpm but also the accelerator feels "caught" or "stuck". I have to give the gas peddle a good tap or kick to free it up!

I currently have no codes to read so I'm stumped.

Could the be the Idle Air Control Valve? Is it tied directly to the gas peddle?
Could it be the Throttle Position Sensor?

Thank you,
Jeff

Check the vac line to the f/p regulator, for gas.....could be the diaphram is leaking......this causes a rich condition which is ok on a cold engine......but not on a warm engine...may cause a hard start/stall or rough idle....

Here is a video to help you test the FPR, helpful part is at around the 1:50 mark of the video.
