Sounds like a bad coolant temp sensor and possibly bad connector. Do ever have to hold the gas pedal to the floor to start it?Any codes in the computer?

I would change the coolant temp sensor also inspect the inside of the coolant temp sensor connector if the terminals are green or blue instead of silver replace the connector also. As far as the security light on thats a seperate issue. You will need to have a advanced scan tool scan your body control module for codes.A basic obd2 reader/scanner wont read the body control module.

Replacing that sensor is the number one fix for that issue. Do you have any codes in the computer?Also the sensor connector terminals were silver?Also where was the sensor located you replaced and what was the part number of the sensor you put in?Just covering all my bases.

Yes thats the correct sensor. Do you have a scan tool that reads live data?Also is the security light on solid or flashing when it stalls and wont keep running when trying to start it.

The code P0341 is most likely spark plugs use copper plugs only and wires. Do you still have a tps code?

See what codes you have and let me know the numbers. ALso the code P0341 unless the coil towers are corroded bad coils arent setting that code.A bad coil would set a missfire code look at the spark plugs where the wires hook onto them look for black carbon powder. ALso look inside the spark plug wire ends where they go onto the plugs for that same powder. Let me know what you find.
