Fellas,

I just replaced all my spark plugs and bought new coils. I bought Delphi coils since the SA told me that is what they change in cars since Bosh were not good. Supposely Delphi are upgraded. I bought the correct Bosh plugs for my car as well.

Before the change, I would get steady 27MPG. When I would fill up, it would show 500 miles to empty, sometimes, even 540. Now, I get 21MPG and I just filled up, and it says 390 miles to empty.

Car runs awesome. Smooth as silk, has great pickup. I did reset the MPG gauge, but it still show very low. What gives?

LOL..I really don't think so? I will see how it is when I am doing more freeway driving. I been driving more in a city since the change. Hopefully it will go back to normal!
