    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...

    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...

    anti theft problem!! HELP

    Nope, no remote. The dealer only can handle from 2003 and younger they say. When I look in the wiring diagram the PATS activates a relay, if I can find that one the problem would be solved i guess. Can't be that hard can it?

    engine stopped

    I dind't replace the battery. The battery is about 1,5/2 years old, could be bad but it works fine all the time. Maybe it's a bad ground. The compass/mpg display on the roof flashes from time to time. Think it's a ground under the dash but I have no idea where it is. Alex
