It could be your throw out bearing. Mine does the same.

 

2011 4 door, 3.73, intake, exhaust, 4.7 throttle body, diablosport 87 tune, 3.5inch lift and 34.8inch duratracs. Run synthetic fluids and i run upper cylinder/injector cleaner every second oil change. Im getting 20+ on the highway and ive averaged as high as 18mpg on a tank. Thats using US gallons too. Depends on a few things. Weather, alt, driver, tire tp, fuel and other factors.

 

Why would a brand new car make that noise?

 

12, manual 3.73 with Falken Rocky Mts 35" with stock bumpers up 3" I was getting 19 mph. Add 1/4" steel Ace bumpers and rails probably 18.5.

4.88 with KM2's I'm around 17.5 mph. I do more suburb and freeway driving, not much city.

 

Do u kno what speed that is for the rpms???

 

Pretty sure it's 70

 

Thanks. Looks like 4.10 will eat way more gas

 

One more question. Is that chart based on my tires are 33" or is it what they are after u measure them with a ruler. Dumb question I know. But was thinking of that. Cuz for my procal I measured the tire

 

2007 4 Door 35' Toyo OC MT's. 15 mpg around town (I live in the mountain :x) 18-20 Highway, No Chip, and MBRP exhaust, steel rims, stock bumpers


I have 4.10's btw xd

 

2007 jku 160000 Kms ,35x12.5 Mickey T Baja ,4" lift, headers,full exhaust, throttle body, air intake, sprint booster and super chip, winch, bumpers and 4:10 auto. 350 KM on full tank city, 400 km full tank hwy / city. With O/D off 350km every tank . So I think that's around 14 to 15 MPG. Don't care just enjoy driving it. :thumbup:
