LS 5.3 swap in a 98 Tahoe. Still working out the kinks to get it running right. I have sloppy 02s that i am replacing waiting on new ones to arrive.
The problem is my IATs. for some reason they climb way up there at red lights and such. like 120+ degrees. and it is night time and 55 deg outside. engine is not overheating.. around 190-195. as soon as i get moving they fall back down.... when they are up high my truck seems to be a bit sluggish. but no misfires... any ideas?
