Thanx Texasvick.

Yes they both do.

All 2003+ Panthers have knock sensors.

Does anybody know if they have a knock sensor?My friend bought a 05 Marquis and my dad bought a 05 Crown Vick and the manuel says for both to use the cheapest regular and not prem.

If i use regular in my '99 it pings like a *********.I tried everything and nothing works.I figure the hot humid climate and the a/c on all the time plus heavy traffic effects it.So i figure they might have a knock sensor but don't know.Thanx
