Detonation at idle possible?
Is it possible to cause detonation at idle? I was adjusting the idle fuel through my pfs last night and realized i was reducing fuel...the car started bucking REALLY bad at 300rpms....is it even possible to cause detonation from a too lean idle?

I really doubt it. Det will damage the engine if the pressure spike at ppp exceeds the engines parameters drastically. If you lean it out ie past stoich at idle i would expect to see the idle get lumpy as the engine is starved of fuel and struggles to combust untill it stalls.

If the motor has no fuel it will do exactly that.
You aren't going to blow your motor at idle or light cruise by leaning it out. The question is, why are you having to take so much fuel out....I would look for mechanical reasons.
