I have a 2003 ford mustang automatic v6 it makes a squeak that sounds like a belt sqeak but I replaced my belt and all the pullers run freely , but it with start to squeak and idle ruff and then when I stop at a light it will squeak louder hesitate an then stall, what can it be ?

 

It's the camshaft position synchronizer. Had the same thing on mine. Parts cheap and the install isnt bad. If I can find the link I'll post it up on the install.

 

Thanks man worries me haven't had it long and it just scares me abit
