Can you guys give me any suggestions. I tried to install an aftermarket intake pipe. The one that I purchased would not work on my contour. I have a 99 SE Sport V6. So I returned it back to stock. No the car idles rough, It shifts out of synk, and it knocks and pings like a pinto when I accelerate. How do I go about fixing this without spending countless dollars at the dealership. do you guys have any answers. I am calling to the contour gods
