I dont think it has anything to do with a bad part, because after spirited driving, the car pretty much idles fine. Def, I think you are on to something for the cold start map. However Yes I do have a lc-1 wideband, but it is nonfunctional. The bastard took a shit the second day I had it. I really need to check my wiring just to be sure it wasnt my fault. Any more opinions are welcome. I will revive this thread if it falls to the wayside when I can get some good wideband readings. Thank you for your response.

Also def, if possible can you explain to me what this lean misfire is doing, and how it is creating this hole in my idle, like I said the darndest part with this thing is that depending on my rpms and how I give it a little gas, she reacts funny, like I said about being able to get it into that sweetspot where it will idle fine for a while, but yet my TB is opened just the same as it was earlier, but it produces a totally different idle. Thanks.
