you could see if the ambient temp reading is relatively close to actual and map sensor is reading correctly, just a couple things that are easy to check without going down a rabbit hole.

Maybe the pcm is adding more fuel when it's colder because it needs it. Gonna get a tune on the new motor?

I think I am going to wait until I replace the trans to get a tune.

been waiting on this stupid control arm to ship from amazon for a month now, because it was $10 less than rockauto.....
canceled and ordered it this morning from rockauto and it shipped already..... tired of waiting... got a road trip in a couple weeks and need to get this front end done
