I am looking for a 99 tiburon ecu mainly because im getting a weird code that showed up at the smog check which sais i can't pass so I need to replace it because my ecu is acting weird, throwing all these codes that when the mechanic checked nothing was wrong so.., I am located in CA where emissions laws are really strict =/. Anyway I need it as soon as possible and just checking if anyone has one on here, just email me please or aim me at nveil2r ,thanks in advance.

 

Any ECU from the years before and after should work fine, and be fairly cheap at a local junkyard.

But the codes don't just throw themselves and electronics DO fail, but not very often... have you got a second opinion (different mechanic)?
