I am new here and have a question.

My 2003 Sedona won't stay idle unless I push the gas pedal
I am not sure if this is a simple fix or require major work. If this require major work how much will it cost to fix it. Thank you so much for your help.

Is the check engine light on? Regardless, take it to an auto part store or dealership to see if you can pick up some codes and start from there. It could be bad Oxygen sensor, clogged PVC valve or fuel system problem.

Could also be vacuum related, check all vaccum hoses.

Welcome to our site!
Take the hose going to your throttle body off, and look inside the t/body if its real dirty, it's time for a good cleaning. I would start there.

I just got a called from the garage it's a bad crank sensors. Charged me $350. Does it sound reasonable ? Can it be a bad sensors ? Thanks for all your help everyone.

Drove home and the car stalled out on me. Took it back to the garage. WTH !

$350 for a crank sensor??? WTF???
A bad crank sensor WILL NOT cause an on going idle problem and if it's bad the car WON'T run at all with or without gas.
I would listen to the guys here as none of us make a cent off of you and WE own KIAs..
There have been a lot of good responses to your plea that make more sense than a crank sensor.
It's your money...
