when i first start my car and drive away it rides nice and smooth. shifts smooth everything. (auto). But after about 5 minutes it has a hesitant start. for about 500 rpms. when its idle and been running for about 5 minutes in park it hits 600 rpms. when i first start it its 1000 rpms. Was wondering if the maf would make my car slightly backfire when letting off the gas / cause a bump between shifts after the car has been warmed up. the injectors are all working properly and just replaced. hoping that this is the maf so i can buy one of you guys. also when i took off the maf plug it has pegs b-e what happened to a? sorry if this is repost.

It's either air, fuel or electrical in nature.

I've got this same problem too. I checked my maf and it's within operating range. Any of you guys dealt with a problem like this before?

its about 2/3 up. when the car is warmed up it hesitates when its a fresh n cold it runs smoothly

ok, so then it relates to when the car switches between open and closed loop modes.
I'm thinking the coolant temp sensor may not be working correctly, but that honestly is just a guess.
check the connector on it it may be dirty/corroded
