Car acting up after Longtube Header Install Ive been running on open headers on my car for about a month now, and since the day i drove it , around 45 mph and higher it feels like its sputtering , a friend of mine told me its because i dont have the rest of my y pipe on there just headers and thats it.it's getting poor gas mileage ,and the main thing is that it lags when i try to floor it . any help would do or suggestions...it also feels like ive lost horsepower

Any codes?
after I did my heads I ran it with open headers it was running kinda crapy it was back firing and crap after I put the y on no problems. YOu might need a little tune.

Not 100% shure on that back pressure thing I think its more that your car is running too rich or somthing along that lines, I have a cut out just a cupple more feet back so I dont think back pressure has anything to do with it, its your O2's that are telling your car how to run. I think that back pressure is like the Easter Bunny.

you need to run some extensions on the ends of the collectors with a turndown or something so the oxygen sensors can get an accurate reading

If you have a code reader you might see a missfire code on it and your SES light will not set.
SO as far as bad spark plug I I dont think so but pull one out if you feal like it. like said above its your 02's reading lean so your car is running too rich thats my guess.
