    My engine is pinging really really badly. It acts just like it did before I replaced the knock sensor 10 months ago. When I replaced the knock sensor it stopped. Well I double checked the knock sensor and the wire is hooked up to it. You don't think it could have gone bad already do you? I'm not getting any codes from the computer either, well my check engine light has not come on, I did not check for codes yet. Any ideas? Oh yea, I just adjusted the timing on Saturday so it's not the timing. And I already use 89 octane gas.
