Thread: rich idle, lean when high rpm and knock?

a friend of mine has a series 2 3800 and he is running -16 at idle and as soon as he passes 300rpm he goes +16 lean and hits over 8 on knock...what can cause this?

nothing she is stock just bought her yesterday oh and its a 2000

checked fuel pressure and all is normal there

check plug gap.

If it's going that lean, and knocking that much, it's probably lean.
check the MAF, TPS or the O2 to make sure they aren't on the fritz?
