99 p.s.

On my 99 when its cold out I think there is some sort of butterfly valve maybe that closes off and the motor runs about 1200 rpm. Is there a way to turn that into an exaust brake? If not no problem is there a way to disconnect it so it won't close off while I'm driving? If so what do I unhook?

well first do you have an auto or manual

It your EBPV you can disconnect the sensor so it wont come on. Look in front of your hpop and you will see a tube coming up with a sensor plugged into the top of it. Just disconnec the sensor from the tube. I have heard of guys slicing into the wires that lead to the sensor and grounding one and making the other one hot through a switch. However it takes a few seconds to kick in, on works at around 2000 rpms and doesn't do much for an auto tranny
