Since I got the car I've been fixing things and making sure it is running well. I was getting 600 kilometres from a 70 litre tank when I got it (highway) and thought that was low (I'm supposed to be getting around 700k, right?).
And sorry to my American friends, not used to gallons but I'm sure you can suggest something anyways.
So last weekend I did the timing belt, water pump, spark plugs, wires, cap and rotor, and a new air filter. I thought I would get better fuel economy because the replaced parts needed it, but instead I am getting a lot worse.
I'm getting now around 515 km per tank (70 litres) and don't know why it would lower and why it is so bad. I drive mostly highway and honestly like an old man. The car runs AMAZING, I'm just confused. It must be something simple, right?
Any thoughts would be greatly appreciated.
THANKS!!!

 

What did you gap the plugs to?

There is no way it would get worse unless something like plug gap was off. Also, what kind of plugs did you install?

 

Gapped to manual specs. Also, used Bosch plugs, wires, cap and rotor.
Any suggestions are greatly appreciated!
THANKS!!
have a great weekend!

 

Use OEM plugs.
