LTFT - is this normal?

[cwmoser]

2002 LX470. Using the Tech Stream data list live data monitor.
At idle my LTFT1 and LTFT2 looks kinda high to me - positive 10 to 14, but at
steady cruising speed at 2,000 rpms both LTFT1 and LTFT2 are slightly
over zero or slightly under zero.

Is this a normal condition or a symptom of air leak?
My LX seems to run just fine - just curious about the data I'm seeing.

Yes, I think your right to look for a vacuum leak. This is a classic sign that a vacuum leak is present, having a high LTFT then lowers to normal when held at 2k.
