What can cause bad fuel economy? I've noticed a drop off in my MPG (1993 Pug 405 1.6i), assuming driving style is the same and theres no leak in the tank, what can cause bad economy? I am just about to set about cleaning the air filter (its a washable K&N).
Any ideas guys?
Cheers

Hmm if I were you, I'd get my engine tuned up. A bad tuning can affect the fuel economy especially if the fuel/air mixture ratio is not optimum. Another thing you can do is send your car for an engine carbon cleaning if it's old.

Blocked/dirty filter, bad air meter? Maybe bad plugs?
get lighter shoes :)
Uneven tyre pressure?
