I have knock sensor light that is on I have auto parts store check it. I ran Lucas fuel injector and the light went off on its own on the following gas refill tank then it came back on again on the 3rd fill. I always use 92 on my gas. What would be the solution? Someone suggested me to buy JB 3 bottles solutions (no idea what it's). Please help!
