I purchased a used Eddie Bauer with the 5.4L, it has 58,000 miles. Yesterday it was running rough and idling rough. It rained really bad and the tempature dropped 30 degrees. I figured moisture in the gas. I put dry gas in and shortly after that I got the "service engine soon" light that blinks sometimes but stays lit. I have also been using super unleaded.

The truck is running better but still rough idling. The service engine soon light is still on.

Any ideas on where to start?

Thanks in advance,
Dan in NJ

Do you have an OBDII Scanner?? I would start there. If not go to Autozone and get a scan from them to get your problem code. Then we can go from there.

Sounds like bad coil (cops). Go to Autozone and ask them to hook up the OBD2 scanner and get the codes.

I guess the Expy's have some issues with COPS, though my 99 Expy with 72K never blew a coild but my newer 03 Expy has already gone through 2 coils.

OK, I'll bite. What the heck is a coil (cops)??? i know what a coil is on the old distributor cars, but this sounds like something different.

I am having 3 of mine replaced today...darn coils...The guy at Pep-Boys said that I will need the others replaced soon...Looking at $50 per coil plus they said that they cause to plugs to go, so they are repairing that too...TOTAL $500 for tune up and 3 coils...4 more to go!!! Good luck...I guess this is not bad compared to the issues that I could have...at the end of my payments so I am guessing that other stuff will go soon...2000 Expy, I would buy another really I would...

I have used these forums extensively. Let Autozone or whomever diagnose the problem for free, beats paying for it! .....

I was getting the same errors. P0306, Spark misfires, Ignition Coil Misfires and others. I have a 2003 Exp. Eddie Bauer with 70,000 miles. I just replaced all coil packs, spark plugs and ICM (Ignition Control Module). I also had to replace a dying battery. In the past, I was replacing a plug coil here and there. It would last for a while then the same rough idle and service engine light. I am fortunate enough to have a brother in law who runs a parts distribution warehouse. But check Ebay and other online sites to save money.

After completing all the work, my engine was running really rough. I double checked everything and had loosened my PCV vacuum hose. After reconnecting everything, the engine ran a little better.

I finally corrected the rough idle after disconnecting the battery and all three connections to the Control Module on the firewall passenger side (EEC). That reset the computer. After I hooked everything back up the truck runs smooth as ever. I don't know if I made a mistake by swapping batteries while the truck was running. Shadetree Mechanics at its finest.....

Update:
After replacing ICM (Ignition Control Module) in May. Plugs in June, Coils Packs in July, checking for vacuum leaks.... The truck ran great until yesterday. Now I am Idling rough. Most of the other misfires were at running speeds.

Should I have replaced everything at once?

I am really frustrated.....

Latest update - cylinder 5 misfire. By luck I went to unplug the disconnect and one wire with a crimp popped out of the disconnect. After putting the crimped terminal back into the plastic connector that plugs into the coil, I haven't had any problems and have put 15000 miles on the truck. I did pull the number 5 cyclinder plug and clean the carbon build up off because of the misfiring.

If anyone gets this rough idle problem, you should check each of the two wires that go into the plastic and rubber connector that plugs into the coil by tugging on this lightly.

This little wire saved me tons of money and headaches trying to figure out what was wrong.

If the instructions aren't clear - email me for pictures. I'll be happy to help anyone out!!

GREAT info! Thanks. I'm new to the forum and taking many notes :)
Today my 03' 4.6L Expedition suddenly started idling up and down at the stop light and in park almost stalling out. The lights dim up and down and the battery light flashed on and off. I cleaned the MAS sensor and K&N filter. Still has a rough idle with up and down RPM's in park. Any sugestions? Thanks
