Knock Sensor

I expected this to be a straightforward fix for my car's issues, and reality matched up well. As a beginner with cars, I found the installation process simple and didn't need any special tools. It's been in use for a couple of weeks now, and my Mazda is performing much better, no more strange noises or hiccups. For the cost, it's a solid choice that saved me a trip to the mechanic. :)
- Pros: This sensor was incredibly easy to install, fitting perfectly in my Mazda without any hassle. It has kept my car running smoothly, just as I hoped, and the price was great for my budget.
- Cons: One issue is that it could be wrong, but I noticed a slight delay in response under heavy acceleration, which might not be ideal for all driving conditions.
