I have a 97 taurus with the 3.0 v6. When I use 87 octane it knocks like crazy. Could this be a timing issue? Is there any way to fix it.

Thanks

Try using a higher octane. If you have a vulcan engine they are more prone to knocking than the duratech or SHO. if not you may have a timing issue.

It does go away with higher octane gas(93). I was hoping to find a fix that would allow me to use 87 octane.
