My 2002 2.5 Millenia would average no less than 20 miles per gallon after using a full tank of gas now it's around 16 miles per gallon.

The car stalled about 3 months ago because of a bad distributor cap so I took it to the mechanic and they replaced the distributor cap, rotator, spark plugs and wires. The problem now is that I noticed the decreased miles per gallon/increase gas consumption.

Do you think the problem I had with the distributor cap has something to do with the high fuel consumption that I have now?

I replaced the air filter today and I will see iit that changes anything. I also I checked the pressure in the tires and it is normal.

Any sugestions on how i can fix this problem?
Thank you.

 

I would say they didn't adjust the timming right when the installed the new distributor.

 

what he^ said

 

check your timing a spark plug gab for correct settings, simple and cheap fix you can do it yoruself

 

that's not quite true. you first have to put the car in diagnostic mode, which involves jumping a couple of pins in the diagnostic connector. and, since i dont have a 2.5, i dont know which ones they is. then you set the timing.
