What can cause KR My car ran fine in Feb. Its now struggling to get off the line in a very bad way. What can be the causes of severe KR? Can there be a physical problem bad enough to cause it? Can an issue with a pressure plate of something in the drivetrain being imbalanced and cause the issue?

Bad gas can cause it. Also, as the weather gets warm it tends to predetonate easier. Try some race fuel and if the problem goes away, its the fuel. If not, you might be getting knock from your exhaust or something like that.

Thats what I'm asking. The exaust is solid and doesnt bang at all. I do have solid bushing LCA's. What about an imbalance in the drivetrain? Anything in the rear? Like say a bearing being bad? I'm leaning towards a vibration issue as opposed to just bad gas.
What else can cause it to drop into the 87 octane table ?
