Default Bone stock Z28 idles smooth at 500rpm?

Any idea's? You guys have already answered one question quickly and correct for me so I figured I'd check this one out also.

I already tryed to use the search function but every other thread on this was concerning rough idle due to aftermarket or PCM tuning.

Great thanks again.

500 RPM on the tach is normal for the A4 in gear (warm) - my scanner showed it actually fluctuating between 525-585.

Might be closer to 550 after seeing the last post, which would coincide with my scanner - going from memory before tuning (wrote down my stock RPM's though). Again, that was engine warm, in D, foot on the brake. P/N warm was 645-676. Might vary a little from year to year too.

Edit: "foot" on the brake, not "food" on the brake.

I think for 99s, 550 was the stock warm idle speed
