Hate to start a thread like this but no option.. im stumped... last night my idle was fine on the way home. This morning as i would come to a stop the idle would dip to 650 and would only recover to around 800rpm of my link set 950 with isc reading 20. it did this consistently but never stalled out and no driving issues other than that.

I got to work and checked the grounding boxes in link and idle was a tad off but not much. I then unchecked the boxes and idle is sitting at a solid 950 in park with isc reading 39(i know it should be 30 but ill take it over 120).

When i put the car in Drive(auto) my idle drops to 700 then recovers to 920-30 with isc all the way up to 105. When i put it in neutral from drive idle jumps to 1500 or so then settles to 950.

What would cause this behavior? Seems like my isc is doing its job but for some reason under tranny load my idles are getting screwed up.
