ok about a month ago i installed a new exhaust header. My car runs fine and i did get a good boost out of it but it now seems to idle kind of rough. It doesn't do it all gears only when its in drive and only when i am sitting still. Is this normal or do i need to check something out?

 

my 95 does the same (i dont have the header though) ive heard the 95s do idle rough due to the proformance cam but i dunno about that. i do know that my car also idles funky because i have an electrical problem, when the windshield wipers go the car dies down a little, when my stereo hits it dies down a bit, and when i turn on the rear defreosters it reaaally dies down, it never has stalled (knocks on wood) due to that but its kinda annoying im guessing i need a new alternator and battery, but who knows till i changem! hope this helped a little?
