So this is pretty much a follow through from this other thread i piggybacked on for a little while
here the thread if u wanna read it.

So i got a 2005 Grand prix gtp comp
i have replaced plugs and wires, tranny fluid and filter
So my issue is that when i first start my car 85% of the time it will drive like its bogged down and will hesitate to shift, when it finally does shift out of first its around 3-3500 rpm and its a hard shift. Its feels like your starting out from 0 in third gear pretty much. Also a sign i have noticed if its going to do this is the car will have a hard start when i fire it up, And there is like a 2-3 second delay if i go from reverse to forward before it engages. If i put the car in park or neural and restart it, the problem is completely gone and the car runs perfect. So i know its not plugs or wires or anything like that, and i don't see how it could be mechanical seeing how restarting the car fixes the problem.
So i looked around on here and found a guy who had the same issue, His MAF was the problem, So i ordered a new AC delco MAF from rockauto, I put it in the car and the problem went away for about a week. Now its started to come back, Ive driven around with the MAF unplugged and the problem is gone, So i know it has something to do with the MAF, Ive checked the wiring and cleaned the connector and its all good. So Im completely out of ideas on this issue, Any ideas?
