Bests & Worsts Reviews from Amazon

What can I say, it saved me a bunch of cash that I would have had to pay at a dealership or tuneup shop. I purchased the unit when I had a check engine light come up on my Ford Escape. As soon as it arrived I hooked it up which was so simple I refuse to tell you how! The trouble code was quickly displayed and I went to the Internet and found the explanation of the code. Back to Amazon to buy the required sensor, sensor delivered and back to the Internet to see how to install it. After installation used the ANCEL unit to clear the code and check engine light. Job done, another happy customer. I almost look forward to the next "Check Engine" light!
