I have a jeep grand cherokee laredo, all time 4x4, v6 and it recently started doing this stutter thing where you try to go but it acts like it is not getting enough fuel, RPMS drop when it does it, most of the time its when im driving uphill, but sometimes if im on level or even downhill. I replaced the fuel filter, cleaned all of the sensors i could get to, including the TPS. Anyone else have this problem? If so what was the fix?

 

How old are the spark plugs and wires? Did you happen to check the fuel pressure?
Oh, it's not a V6, you either have the 5.2 V8 or the 4.0 I6.

 

I apologize, it is the I6, im not sure about the plugs and wires, i was thinking fuel pump, when i turn it off when it does it and turn it back on while driving it usually stops doing the stutter

 

I just put in a new TPS and it is doing the exact same thing, very random, sometimes it wont do it at all, other times i can barely get where i need to go. It seems like it only does it when it is warm, anyone have any ideas? I dont want to go and get a 400$ fuel pump put in if i dont absolutely have to..
