im considering changing the dpfe sensor first and if that doesnt work the EGR valve too ...its alot more expensive....im going to order non ford oem , standard motor products is what i found on searches....should be ok
there are PDF files in the previous pages with diagrams and it doesnt seem that complicated, remove the negative terminal connection on your battery first ..... then remove screw and clips for hoses etc. plug in the new dpfe and egr to connectors and put hoses back . If your mechanic does it they will probably charge 1 hour labor .... maybe half hour if you are lucky
Ive already spent 1000 dollars canadian or about 700 USD on new sparkplugs , rear differential fluid and new programming as per mechanic and dealer advice.... still have the problem although its a bit better now , seems like 89 octane gas helps a bit as 87 I was using before.... doesnt run as rough ....
