You are mis fireing on cyl 1 and 3 if you replaced plugs and wires and coil this is going to be a fuel injector issue or valve issue. See if you can swap the injectors with known good cyl. and see if it changes. Or have a shop do a fuel injector service on it to see if it helps. It may be to late for the fuel injector service.

98 FORD EXPEDITION ACCELERATION ISSUES


Do you have a check engine light blinking when this problem occurs? I assume you do because if it is missing and sputtering like you say the engine control computer would detect that and turn on the check engine light. Next step is to have the systems fault codes read through the diagnostic port under the dash in front of the driver, Autozone and others does this test for free.

Check the idle fuel pressure. Load the electrical with headlights and heater defrost etc and see if problem gets worse. Attempt again with all accessories off. Could be fuel pump is getting low voltage at idle or fuel pump is failing. Bad fuel pump would definitely be a problem high fuel demand. Check vacuum line between pressure regulator to intake manifold.

Check for a air leak in the intake manifold. Gasket/hose etc. The P0171/P0174 is an indication that not enough fuel or tow much air. You can sometimes hear the air leak during idle.


Best solution is to use a graphic capable scan tool and watch the fueling trim/idle.

If you do not see a distributor or spark plug wires, then you have a coil over plug system. Changing the coil pack is as easy as removing the hold down bolt and lifting the coil pack off the spark plug. Other things should be checked like signal to the coil, the fuel injector signal and the spark plug

1 through 4 is on the passengers side and 5 though 8 is on the drivers side, and all in order.

Misses during acceleration , rough acceleration, service engine soon light on, power loss, still runs fair, 2000 ford expedition


Go get the codes ran at auto zone or advance auto parts they will do it for free. If the codes come up as a cylinder miss-fire then it is most likely a coil (being a ford). Write down which cylinder it is. I wouldn't replace any of the spark plugs , useless you have more than 100,000 miles. If you have to replace the spark plugs use BOSH double plautim or better. The cylinder placing is ( as your are looking at the front of the truck) passenger side front to back 1-2-3-4 driving side front to back 5-6-7-8. If you never seen a coil buy one so you know what you are looking for. The coil is held in by a 7mm bolt. Take the bolt out and replace the coil. Problem Solved. Estimated time 20 Mins with 60 dollars per coil.

Misfiring


An O2 sensor will not cause a miss, period. I would think the problem may lie with the #3 coil, or the wiring to it. What are the trouble code(s), give me those and I can be more helpful
