hey guys, a little help if you will. I have very basic knowledge on cars
and any advice would be appreciated.
I just got a 2001 Sunfire and i would like to get the best bang for buck out of it as i can. I would like to make small cost effective improvements to the car if i can so that it runs better, and maybe gets a little more horse power and/or gas mileage. for example i have been told i should look into getting a Delphi fuel injector-$90. Any suggestions along this would be greatly appreciated.
Also if anyone could guess as to why the car would make a constant tapping noise that increases with acceleration it would be helpful.
