There was guy that i met and talked to about it on another site like this amd he seemed like he knew what he was talking about amd even came out and tested some of them on the car and he did it free of chrage so i dont see why he would lie i just dont understand why a aftermarket version couldnt do the same? ---

Yes. The vehicle manufacturer doesn’t make the O2 sensor. The O2 sensors are purchased from a vendor/supplier to be installed into the vehicles. So the O2 sensor that’s in the vehicle was probably made by the same company that sells O2 sensors at the parts store. Tester ---

All the O2 sensors I’ve installed came from CarQuest. Never had a problem. Tester ---

Try this. Turn the ignition switch on so the dash lights come on for a second, and then turn the ignition switch off. Repeat this three times and then leave the ignition switch ON. See if the Check Engine light starts flashing. If it does, the Check Engine light is flashing codes. Now all you have to do is look up the codes for a Chrysler that flashes the Check Engine light.

Tester has provided excellent guidance. He’s also beautifully described why aftermarket parts are not problematic simply because they’re aftermarket parts. I will only add that I personally have had problems with Autozone parts and would recommend going elsewhere. AZ seems in my experience to sell some junk. Try a parts supplier that supplies the local garages. ---

Also do yall have any suggestions as to increase the braking strength on the vehicle because it brakes to slow and if needed to brake quickly in a short distance would most likely result in an accident ---

Chrysler cheaped out when it came to the brake components on the 300. A big heavy vehicle with the brake components on the Neon. They did the same thing on the mini-van. Tester [Next page](https://community.cartalk.com/t/chrysler-info/97483.md?page=2)
