Picked up a 2000 Expedition 5.4 Eddie Bauer 4x4 175k miles I think after wrecking my 98 expo. Got it from a local guy said it had a little hesitation at idle but wasn't really worried after having done everything on my last truck figured probably plugs or coils. Got it home pulled throttle body, injectors, coils and plugs. It has a aftermarket intake that looks some what new Plugs were nasty and plug wells had oil and old coolant in them so cleaned them up best i could. One of the plugs I couldn't get a socket on when i went to pull it so peaked in and there was a washer jammed against the plug figured well that had to be the issue cause it would cause a misfire. Installed new plugs, the coils seemed OK (didn't have money or would have got new) I through new boots and springs and cleaned and rebuilt the injectors. Cleaned the IAC, EGR, MAF and throttle body before installing. Through a fuel system cleaner in the 1/4 tank and fired it up. Sounded way better not shaking as much but found PCV boot leaking fixed that and it smoothed out. I reset the OBD2 and took it for a short drive. Dosnt have the power it should and exhaust dosnt sound right above idle and engine still has a little shake to it. Vacuum gauge reading are normal, pulling one of the EGR tube hoses and with vacuum gauge it sits right around 0 while idling and fuel pressure sits at 40 with key on engine off and after 5 or 10 min didnt drop but maybe a couple points. Oil looks ok. I banged on the muffler and i can hear a little bit of crap bouncing around but not a lot banged on the cats didnt hear anything. Ive sprayed carb cleaner all over looking for leaks. I have driven it up the road a couple short trips. It has not thrown a check engine light but i haven't driven it far enough for the O2 monitor to be ready yet cause don't want to do 65 down the hwy with something wrong. I attached a link to video of my live data the second pass through i am tapping the throttle sorry its blurry.
Pulling Vacuum the EGR tries to kill the motor so seems to be working but after 45 min of idling the EGR and tube were not hot.
I pulled the Vacuum line off the fuel pressure regulator and there was no change.
Does anything stick out to anyone?
What should I try? I don't have money to throw parts at it.
Thanks for any help
