Where is the location of connection for scanner

Take your car to a mechanic shop or autoparts store and have them read the computer.

If the battery has just been replaced or discharged this could be normal.

With a battery disconnect the learned calibration of the cars computers are reset to factory settings including idle,

The car needs to relearn the idle and running settings. It can take several minutes and driving for this to occur. The car will in many cases want to stall during this learning cycle.

Note this problem usually will only occur during battery replacement or discharge.

If not associated with a battery disconnect then borrow an OBDII scanner and read the codes. If the car is derivable take it to your friendly auto parts store for a complementary scan tool code readout. The computer information will lead you to the likely sensor culprit.

Hope this helps?

it sounds like it's the idle air valve this controls the idle and drive rpm's when you step on the gas does it sometimes at idle go up & down by itself repeatedly? it could be something hitting the throttle and when you press down on the gas or shift it is knocked out lowering to normal idle/rpms, the tps is on the throttle body and is connected to the throttle lever and most likely right on the other side of the lever a little switch with a electrical plug on it search it so you can see what it looks like if you don't know already they are sealed and can not be cleaned you must replace it try checking with the car in park engine running and raise the idle by the throttle lever if it goes smooth up and down return to rpms that's not it if it races or sputters and then raises up that's it or it could be both units are blown out needing to be replaced

Run the scanner/computer for easy diagnostic and fix it.God bless you
The electronic in vehicle now is very complicated. see the diagram attached.

check your fuel pressure and fuel filter it could be a fuel issue

have light turned off with scanner, or drive it a few miles to see if it goes off. just because the sensors have been changed the pcm thinks there is still a problem and keeps light on. turn off with scanner.

usually idle that goes up and down is cause by a bad "idle control valve" located near the throttle body. Needs to be replace.

try cleaning your idle air control valve. located on or around the trottle body.

Check engine for vacuum leaks at all hoses, hose connections, intake gasket etc. I have also seen retarded engine timing produce low vacuum. If no leaks, check anything in control system that controls timing...however, I believe you will find a leak before you need to go there. Also check Idle control valve and egr valve for malfunction or blockages.

ok there is a loose wire and when your rpms get to arround 5-6 im sure your motor starts to wiggle and jiggle a bit and they touch thats where your cut appears but at idle id think they are apart eanough to keep the electricity from jumping get it checked out at a mechanic or try and locate the wire yourself
