does anyone know how technical changing the Turbo Bypass Valve on a 98 900 is? From what I have been able to read on here, I think that is whats wrong with my car (stalling at stoplights, rpm's going up and down when idling, etc...). My dad can do most simple mechanics, but i want to make sure i dont buy the part and get him involved in something over his head. any thoughts would help!

 

are you sure that it is that which is the problem? It sounds like the IAC (idle air control) valve. That is a really simple replacement and you could try cleaning it first before replacing. They can be costly.

 

I guess I can't really say I'm sure until I actaully try it, but I have tried cleaning the IAC valve to no avail. Any futher ideas about the Turbo bypass?

 

the turbo bypass valve is an easy replacement. Around 2 clamps and a vaccum line.
