well as you can tell from the title i installed headers on my car jvtr racing headers. i have a 2003 hyundai tiburon. and as soon as i started my car up it went all bad. my engine is idling at 2500 rpm. it feels weird to drive. my check engine light is on. and i dont know what i did. i tightened everything right. i had to of. and i put back the engine the way i took it apart. i did have a problem with the throttle cable. for some reason when i took it off when i went to put it back on both nuts had moved...and your only supposed to move one and keep the other as a fail safe. and now when i drive it has this putt putt sound..kinda like a sprinkler. i just dont understand. help me out on what it could be. anything would help cause i gotta pretty much take my engine apart tomorow and i would like a little headstart as to what im looking for.

and is it possible that the headers arent flush...i did use a hellof strength to get the bolts underneath on...ne one please



thank you
