Car is idling up and down cut off at stop light hesitating while driving
I suggest you get your throttle body cleaned 1st and see how that goes
Also check for vacuum leaks by spaying easy start around inlet manifolds and any vacuum tubes. If the revs increase then you have a vacuum leak leaning out your fuel mixture
I would probably check for a vacuum leak. Still could be a fuel problem but would be more steady or a miss.
Could be fuel injector, also could be Engine Speed Sensor (Crank Position Sensor) is the Check Engine Light on?
With all the problems with your car (Over 100) - find something new!
TPS, Sensor will idle up and down as the anti knock sensor will also
SOURCE: engine light is on ,code P0171, hesitates when start driving
you will need a code reader to turn light off

This a problem with a vacuum hoses leak. Need to find the leaking hose due to cracking and joint rubbers degrading. Need to have a Mitty vacuum gauge to check these plastic hoses one by one to replace bad ones or replace all of them. If you don't feel comfortable to do thi,s have a shop find a vacuum leak for you.
SOURCE: When car is sitting idle; I hear the hesitation.
It could be the fuel, especially these days with the different suppliers and additives, not to mention the extreme moisture in the air & seeping into the fuel tanks at local stations.
If you know your car doesn't need a standard tune up, the air-filter, fuel filter, and spark plugs have been maintained and are working properly you may just need to have the injectors cleaned, or use a little fuel injector cleaner every few tanks of gas to clean them up.
I always fill my fuel filter & those I'm servicing with fuel injector cleaner when I replace them. (1/2 full) This has seemed to provide ample cleaning for most as I've never had an injector issue return to me.
Try some regular fuel injector cleaner available at wal-mart or any parts store. Not the expensive bottle that claims it will make your car perfect just the regular 2.99 a bottle stuff. When your car is at about 1/2 tank on the fuel gauge, add a bottle & drive that tank to 1/8. After refilling later & getting down to about 1/2 tank add another bottle. This should do some good if you're talking about hesitation & minor idle changes that don't trigger sensor problems.
Of course if any of the parts mentioned need to be replaced, this would be the time.
good luck

You have a misfire whether it is from the coil or spark plug boot a full tune up with plug and wires and maybe even ignition coil (coils due short out)
