I just put in long tube headers, no cats, x-pipe, bullet mufflers. My problem is that my service engine light keeps coming on and the car runs rough at idle, and sometimes it goes dead. I just put new o2 senors on the front, and i have the simulators on the back. The code scanner says the system is to lean not getting enough gas. I was going to change the fuel filter will that help. Suggestions needed thanks.

Check the fuel pressure. Your fuel filter might be clogged enough.

Are you running a full race header or do you have the AIR tubes? If so, did you put the gaskest back under the AIR flanges? Make double sure all exhaust connections are tight and leak free. Air leaks anywhere will cause problems. Make sure no O2 sensor wires are lying on the headers. Make sure you hooked up all or any vacuum and electrical connections you may have disconnected during the install.

Thanks i'll check. I think the headers have a little leak?
