Marc: "It's normal." (hesitation / off idle sag)

[Schrade]

Yep - just got off the phone with him; was looking for the PCV crossover hose.

So we were talking about my mill, and I explained what I have goin' on here. I told him about the perfect idle, and how it hesitates around 1.6% TO.

He said (I'm paraphrasing here): they ALL do it; it's because of the ECM's operational coding. Yup - that's what he said, or something along those lines... He said if I fixed it, I'd be fixing 7,000 LT5's!!!

NORMAL.

Looks like I have been chasing wild geese (and a few other things to boot here)

It's NORMAL. If Marc says it, I believe it.

Started in October, chasing wild geese. Holy COW!!!







Well, get it all zipped up, check DataMaster to see what's there anyway, and DRIVE.

Last plenum bolt, found with seeing eye cam!!!
