Help with BBTB over reving - Hyundai Performance Forums

billg401 · 05-30-2004, 12:58 AM

Ok, We just installed the BBTB from Evo fusion today. We reset the computer by diconecting battery terminals, but now it is over reving at Idle. The RPM's at start up are ok, 900 or so, But once you get driving the idle won't drop down below 2700-3000 rpm. Is it possible the tthrottle position sensor isn't working right, or could it be sticking open, Or is there something That I need to know to fix this. ANY help would be great. Thanks.

My car is an 03 v6 tib.

make sure the idle adjustment screw is not in too far..this seems to be a comon probmlem. Or call SharkRacing..er Evo fusion and ask them for a new one.

Follow the cables back a little and you will see a bracket with some adjustments screws. Lossen those a little so there isn't as muct tension on the cable.
