Look at the end of the collector (header) is there a pair of cables ? if not then you have an aftermarket full system. if so and it dosn't move. you can disassemble the valve and clean the pushings but do not grease it or the grease will just burn off and stick the valve again.<br>Go to the FTP site for the pdf of the manual<br>Let us know how you get on. <br>And welcome to the hood...<br>Jim<!--EZCODE EMOTICON START :cheers --><img src=http://img.photobucket.com/albums/v209/ ...

i looked at the collector and no cables but i did see the outside of the exup valve (opposite side of can). it looks like it has been disengaged. ill try to get some pics of it so that someone can tell me what i need. - tone <p></p><i></i>
