FEH TERRIBLE MPGS 11mpg!
Hi, new member here, long time mechanic, first time hybrid owner.
I just got this 07 FEH 4x4 a few days ago. It's got 141k miles on it. I'm getting rotten gas millage. 11mpg! The first day I was driving it, it wouldn't go into EV mode at all. Though it does work in assist. I've since replaced the HV battery air filter. The ac wasn't working when I got it either. I've put Freon in it, and it's holding about 32lbs pressure on the low side. The air blows cold, the line going to the HV evaporator is "beer can cold". It's going into EV mode now, but rarely will it stay on in acceleration, and never much above 20mph. It's idling above 1000rpm (not sure if that's normal). I pulled the duct out of the cargo bay and verified the fans are working in the battery. The recirculate door is functioning also. I pulled the beauty cover off the engine. It appears nothing has been serviced recently, everything has typical dirt on it. I'm gonna try throwing new plugs in it, and replace the fuel filter. Probably clean the MAF too. I checked the coolant levels in both reservoirs, looks fine, and clean. I scanned it with an OBDII scanner. No codes of any kind for a typical scan, though I don't have a Ford specialized scanner to check the BCM. Anyone have any advice or suggestions? I hope the HV battery isn't at fault here, but I'm worried. |

11mpg sucks for a 2.4l 4 banger
the 3.0 L 200 HP V 6 gets about 22mpg average on fuelly you get the same MPG as a H2 hummer :omg: 6.2L engine are you sure someone is not stealing your fuel ?? on the worst possible day you should get like 20mpg... even if the thermostat was open running straight 6.0L v8 mode i get 18.5 on this rig at 11mpg I would have to keep the throttle at 3500-4500 rpm i'll end up hitting the speed governor if I keep it at that rpm |
