Review on Unleash the Power of OTC 3108 PocketScan Code Reader: Scan with Ease and Efficiency! by Jason Cartwright

I have replaced several ignition coils on my car over the years. I took it to the dealer multiple times and had to pay hundreds of dollars for diagnostics and labor. I found that I used this to identify the cylinder that needed a new coil and then just replaced it myself. Fast and easy to use. It has some limited sensor data, but I don't use it for that.
