My scan tool keeps picking up on sensors going bad. First it was the camshaft position sensor, then the knock sensor, then the vvt solenoid, now it's the map sensor. So tell me: am I passed the point of just dumping this thing in the river? Or will I eventually see the light at the end of this unforgiving tunnel of sensor issues? I've replaced everything but the map sensor so far. I replaced one thing then another goes bad. I'm hamster wheeling bad here man. The parts are cheap so far but I'm tired of working on her. Should I keep working? Or leave her to be someone else's problem?

Scan tools are not bad sensor detectors. The trouble codes never say that. They are usually more specific about the symptoms, and are clues to where the problem might be, so please provide the full code number and description.
The vehicle computer reports when sensors give unexpected or missing signals. That can have many causes ... broken wires, bad grounds, poor charging system performance, etc. Throwing new sensors at codes just makes you poor, doesn't get you closer to finding the issue, and often doesn't even fix the trouble light.
It's 13 years old and a GM product. I believe those cars had the same infamous ignition switch problems as my '09 HHR did and the Cobalts. GMs are notorious for electrical problems, especially that platform. My HHR had bad speakers in the back doors and it was barely 5 years old when I had it. People know they have issues and you won't get much for the car if you try to sell it. You're also going to pay through the nose for anything newer. I'd drive it until it drops. Saving a couple hundred bucks on sensors (use only OEM) isn't worth thousands and thousands on a newer car. You learn something every time you work on it.
