    Shutting off EGR

    I was wondering.... How would shutting off the EGR system effect my 5.4 engine? By shutting off I mean closing the inlet on the TB? Some say it would be better but how about the fault codes etc. when the EGR is clogged? Inlet cl9osed or clogged EGR, the same right? Asking this...

    Egr, dpfe, p1401, p0401

    I replaced the DPFE, ereased with OBD and code is still not there. Now the engine only hesitates sometimes when accelerating with a warm engine. Cold it's doing fine. I noticed a damaged wire to the cop, repaired that. My coolant temperature is going up to 98/100 degrees Celsius, OBDII says...

    97 expo dont run right

    When you shut down your truck the EGR is making a sound, thats the vacuum coming of the system. EGR valve check- running engine, put a hose on the vacuum connection on top of the valve and suck on it. You will notice that the truck is going for a rough idle or will die. If so that works...

    Egr, dpfe, p1401, p0401

    It's a 5.4L EB from 1998. I checked with a wire if the EGR port was open, infact I checked them all with a steel wire and at the 5.4 there is one big hole. What I can see on the picture of the 4.6 there are 2 holes. The elbow on the back of the TB was very narrow by the vacuum of the TB...

    Don't know why it is not possible, but you have to check if it's usefull to do. When the intake of the airfilter is smaller than the intake of the throttle body, then it's usefull. Like running with you're mouth closed otherwhise. I did it on my 1998 5.4 EB and you feel a difference. good...
