Chevy & GMC Vans

Hey guys,
At idle, does your timing on the scangauge float around? Mine switches contantly between 16* and 21*. Out on the highway it's steady as a rock at cruise.

I don't looka t it much but I don't recall it jumping around. I'll bring it up next time I'm idling the van to warm up to double check for ya tho.

I think mine always says 16
