Question about 1998 Ford Expedition

2 Answers

Had an ignition coil replaced at about 72,000 miles when the check engine came on and the truck began running rough. The check engine light is on again at 78,000 and running rough the same as last time. Can I replace the rest of the coils? If so how?

    I have the same problem with my 4.6 engine 2001 Expedition. I had the #4 oil,booth, and plug replaced in march. Problem improved, but not solved. Problem resurfaced again in July. Service advisor stated #6 coil needed replacement along with Head gaskits. In the process of replacing head gaskets, technician stated left timing chain with tension needed replacing. Haven't gotten vehicle back. Not sure if this will solve my problem or not.

When my SLP light comes on, my 2002 Altima will not accelerate. When it goes off the car operates fine but the check engine light stays on. what does the car need if the SLP light comes on from time to...


On many nissan altimas I have found bad ignition coils. Usually one bad one will creat a problem. The slp gets gounded through the ignition coil. When the ignition coil is going bad it shorts out other systems. Go to autozone or use a method to retrieve check engine light. If i knew the code it would be helpful. When the car is running rough disconnect one ignition coil with car off. Restart car. If car runs worse that means that coil is good. repeat process. If you have one coil disconnected and the car runs the same that means that ignition coil is not sending spark to your spark plug therefore creating a misfire and making your car run rough. That check engine light is most like likely linked to your slp light. If you find a bad coil using this teqnique replace it, your car will run better. I would like to know your check engine codes and this will determine problem better. If you have a misfire code or a po1300 code that points towards a bad coil

Check engine lite truck is running rough


You should have the light scanned, but you most likely have a misfire. You will probably end up replacing spark plugs, wires and/or ignition coils. That is the most common problem for a running rough issue.

Random multiple misfirings


Here is a list of possible causes. You should not drive the vehicle if the check engine light is flashing all the time, you can cause even more damage. It could pay to have a professional find the real cause.

Spark plugs that are incorrect for the application, cracked, improperly gaped or worn can cause the engine to misfire or run rough at all times.
An IC module that failed to correctly control the ignition coil(s) will cause the engine to misfire or run rough at all times.
Poor connections, broken wiring or wiring that has shorts to ground can cause the engine to misfire or run rough at all times. NOTE: Check connectors that might be pulled apart as the engine flexes or wires that short to ground as they pass near brackets or shorts to ground on the exhaust manifold.
Fuel injector(s) that are shorted, plugged or partially restricted can cause the engine to misfire or run rough at all times.
An ignition coil(s) that has low output, corrosion on the coil tower(s), is carbon tracked or arcs to ground will cause the engine to misfire or run rough at all times.
A PCM that failed to properly control the injector or ignition timing will cause the engine to misfire or run rough at all times.

99 taurus running rough smells funny light flashing


The reason the check engine light is flashing instead of on steady is because it is missing bad and the car companies did this to tell you to stop the car as soon as possible to prevent damage. That is the only time the light will flash off and on instead of being on steady.
The cause is a little harder to diagnose. It could be a fouled spark plug, a bad plug wire, an injector, stopped up fuel filter. I can't remember if that car has the distributer or the coil packs but you could have a problem there. If you have never changed the spark plugs or fuel filter, it is well over a hundred thousand miles to do so now. They say to change them at one hundred thousand but 50 to 75 thousand is better and you will get better mileage. The fuel filter needs to be changed every 20 thousand miles now days because of all the cheap gas we have to put in the cars.
This is for mechanics or technicians. If no one out there believes me about the mileage on the fuel filter, then take the filter off and see what comes out the back. Looks like black water to me.
