this 94 2.3l has gone through 3 dpfe. it has #4 in and seems to be ok...now. it gave off 337 code koeo, and memory 327, 337. replaced dpfe and light went out without me clearing codes. Does anyone have any clues? I am thinking of cleaning the pipe that connects on the egr valve, since I have read that the dpfe is sensitive to any carbon/dirt etc., that may be in there. I understand there is a orifice in that pipe between the 2 pipes that connect to the hoses on the dpfe. while there, anyone know how to prevent the hoses from heat welding themselves to the small pipes from which it reads exaust pressure? one hose is from auto zone, one from dealer. they are the special hoses for this application. Also, egr valve gasket very well secured to engine side of assembly, how is it advised to remove it? not much room so close to firewall, maybe someone had used an adhesive there, I don't know. BTW, dpfe is mounted on the firewall. thanks in advance
