SOURCE: engine misses when placed under load

replace the plug wires this will fix your secondary ignition breakdown. the egr code is due to a bad dpfe sensor which is for back pressure on egr valve.this will not cause misfire.

My eclipse has developed a misfire after it has been driven for about an hour or so! after the engine really warms up the rpm gauge will spike slightly and the car will shutter a little bit and it slowly...


You didn't need a different distributor,just the sensor in it,if it was bad. That now appears questionable.
When it heats up,your ignition module,is breaking down, under load,and your getting a misfire. That would be a possible cause.
Codes don't always indicate a bad part,only the symptom, of the real issue. e.g.(Misfire)

2000 expedition 5.4 lt run fine when cold when warm misses bad anyone know whats wrong??


a very common problem for the 5.4 fords is the coil packs going bad. normally misfires once heated up and under slight load ( in overdrive going up a grade) if the check engine light is on, it can help pinpoint which cylinder is misfiring. if plugs haven't been replaced within last 50-60k miles, plan on replacing plugs, and usually the coil pack that goes bad is one of the rear ones, but impossible to tell without a scan tool. if you don't own one, take it to a shop
