i have a ‘09 Avenger. She’s the first car I’ve ever bought by my self, and she’s very important because it was my grandmothers. I’ve replaced the alternator, I keep up with oil changes and routine fluid check ups.. but lately, I’ve noticed that when I idle, it’s rough. Lights flicker occasionally, so I check the battery but “it’s all okay”. These past few days, now my electric throttle body light turns on and my check engine light pops on. The check engine claims there is a coolant system issue, but My car doesn’t over heat. I hear liquid moving when I first start my car, so I assume it’s a failing heater core? I also don’t smell sweet scents from my vents so I don’t think I’m burning coolant. My main concern is the Electric throttle light popping on. I restart the throttle when it comes on, and it goes away. My car doesn’t go limp either when the light comes on. I was thinking about replacing the ETB, what would you guys recommend?
