Hi there, was wondering if anyone hear experiences pinging on their Northstar..mine pings even with premium top tier gas in it. My 2000 Deville and 2001 STS never pinged and i used mostly regular in them...shouldn't the knock sensor be retarding the timing or something like that so this does not happen? Car only has 50k miles and dosen't have any codes

I think the onboard diagnostics where discontinued after '05 if I remember correctly, so you'll have to use a code reader to pull them or take it to a parts store that will do it for you.That would be the place to start.

Damn, well that doesn't help.

Yes, the knock sensor SHOULD detect a knock and retard the timing and it is monitored. That's why I suggested checking the DTC's. Have you checked for a vacuum leak, causing it to run lean?

P.S.
Sorry, I missed the last sentence in your first post.
