Question about 2003 Ford Expedition

1 Answer


I believe this may be a bad coil, according to a Ford mechanic I met. My question is,How do I find out which coil it is? Can I just disconnect them one at a time when it is acting up?

    I'm having the same problem (03 Expedition 4x4 XLT) but I thought there was more than one coil. I had the problem about four months back and a coil was replaced. The recommendation was that all should be replaced with a much higher cost so I had them replace the one. Was I ****** punched by the mechanic?

    I had this same issue and it ended up causing 2 cadalitic converters go bad costing me over $3000 to fix.

    Now am having the same issues and no codes, but now dying on me and overdrive light blinking.

    Can't seem to get a answer from anyone expert or not.

    how bad is it missing? does it do it during acceleration ? give me as much info as you can. the best and easiest way to tell is put it on the computer. you can try autozone cause its free . but a lot of times they can't tell you exactly which one its misfiring on.a local garage shouldn't charge more than $100 to run it but it will save you a lot of time. plus for your info the coils are a pretty hard job to change especially if you don't have the proper tools.

Check engine light on? Any codes? Missed before and after the cap was changed? Or is the cap new so you assume its good. I have had caps bad out of the box.

My ford econoline 1997 e250 has intermittent misses at idle and acceleration cruising speeds

One of the coil packs are starting to go out. One way you can pin point it is to buy one coil pack and replace one. If it still misses keep moving the spare one to the next coil pack until you find it. If you take it somewhere to be fixed it will run about $275 for each coil pack and up from the dealer. If you do it yourself and some time cost will be $70 for a coil pack. I know cause I just went through the problem at 120,000 miles.

Have You Changed The fuel filter? Surging at higher speeds or cruising speeds, My guess is fuel filter.

if your truck is too new, that will only increase the problem.  try to find the mis fire like you said, but instead of just disconnecting the plugs one at a time, take the plug out, ground it to the block and have the wire connected, there should be a bright blue spark, a yellow or dim spark is a sign of weak spark ad cold be the missing.
if the spark brain is bad, it will cause the truck to mis fire spastically, with no rhyme or reason.
if this does not solve he problem, check for cracks in the distributor (if you have one). make sure everything is   1-dry   2-clean
if it does solve the problem, after you get it running right on a dry day with the engine hot, and running, spray some silicone sealant on everything electric, and let it dry totally before shutting off the truck.
