Hello guys im new to the forum but ive been using it as a great source since I bought my 5.0 mounty a year ago.
Anyway My 98 5.0 has an issue where I am havung constant vaccum at idle to egr which causes misfire, stumbing, and very rough idle. Its smog time and I need to figure this out quick as I get lean and misfire codes with egr hose from solenoid connected to egr. With the hose disconnected it runs great which has caused me to leave it disconnected while I fix the issue. I have installed new dpfe,solenoid, and have tested egr which holds pressure and is in working order. Anyone experienced anything like this? Thanks everyone glad to finally be a member!!
