one last thing,,, does the car seem to be getting quite r or have a hissing sound to the exhaust. could be plugged cat. i dont think that would explain the code though. oh well a thought anyways.

 

already replaced cam sensor and installed a new cat converter,,one thing that keeps bothering me is i bout a egr valve and a ignition module with coil packs for a local salvage yard,both were tested and seem fine,,could either of these show good and when engine warms up start to break down or something,,btw thanks for at least trying to help here its appreciated alot
