Awesome product, had a check engine light for a loose gas cap, tightened it, would not clear, bought a new cap, installed it tight, would not clear, I hooked my new diagnostic machine to it and it cleared immediately. Very happy with the great product at an unbelievable super price. Lowest price in the automotive stores was $50-500, I bought this for $20.
