Hey guys, so I've been noticing as I'm on the highway and I'm just cruising / hauling something when I come into around 3rd gear or a hill where the motor RPM would go down after a up shift it would start to hesitate or sputter (whatever you want to call it) id just simply give it more gas and it would come out of it. Also I have noticed when I get on it at a higher speed it would do it as well some times. I also had an instance where the check engine light would come on and flash. Any insight to this? I have 184k on it. could it be the fuel pump? since they don't have a filter on the rail, or it being on the pump itself, in the tank.
