I useed your segestions and did the B-12 through the vacuume ports on the UIM worked great! I did that first and hardly saw any carbon deposits in the UIM however I was getting code 401 and 402 I then took the trodle body off and the passages for the EGR we stuffed full of carbon then I cleaned that off I only saw one whole there on the right side looks like it come straight from the EGR vavle area. I didn't see one on the other end (left side) is there one ? I now only get code 402 and before my EGR was able to take the hose on the top with no porblems when I attached it this time the car begain to run ruff and then stalled. I am not sure that I have the vacuume tubes run right int he first place. Is there a place I can view the vacuume routes? I took them off and don't know that I put them back right could a mixed up vacuume tube make that happen when I took the EGR out to clean it I sucked on it and the vavle at the bottom opend up and closed when I did that. do you think I need a new EGR valve or is it the EGR sensor? ANYONE HELP with knowldge!!
