What is your question?
where can I find diagrahm for removing and cleaning an EGR valve on my 2001 cad. dts? Will this help the o2 sensor to function properly?

depends on what problem you are having. in most cases no. egr valves get replaced and not cleaned. the parts that are carboned up are not accessable for cleaning. what is your original issue? Roy

ok. the rubber bladder or gasket from the intake to the throttle body is known to split and produce a vaccuum leak. this leak will cause the exact issue you are encountering. have it checked to confirm. the part is cheap but the labor is 2 hours. Roy
