are the tyres bigger than the last set?

 

[tatty]

As scooba said, did you put bigger tyres on?

265/75R16s are larger than standard by at least 5%. That's the problem. The ratio from the crankshaft to the road has now changed so your engine has to work harder to make the vehicle move. Your fuel consumption will rise as well, even moreso in traffic and up hills.

While your speedo might appear to be reading more correctly now, your odometer will now be out by 5%.

Going from 265/70 too 265/75 isn't that much of a change, u shouldn't even notice it. I went from 255/70 too 285/75 and have had some power loss but it isn't that bad. Will be getting it all back and more soon.

I didn't notice the change in mine and fuel is hardly noticeable at all (2.5l). Maybe blank your EGR, cheap and easy to do. There are plenty of threads on here with how to instructions.
