1998 Ford Expedition - Page 8 - Answered Questions & Fixed issues
Why does my 98 expedition make a pinging noise at 25 to 35 mph then goes away
this noise is detonation. It is an uncontrolled untimed ignition from hot spots in the combustion chamber igniting an incorrect air/fuel mixture. IT is harmful if left un repaired as it has the capability of melting holes in pistons.. Run the fault codes or check /change the air/ fuel mixture settings and ignition timing of the engine . Most engines run around 10-12 degrees advanced and any more than that will help cause the problem, as the spark occurs too early and the extra pressure built up by the combustion will combust the rest of the mixture in the cylinder. Fuel quality is important so if you are using a standard grade fuel( 89-91 octane rated) fill with a premium fuel with a higher fuel octane rating . Give a miss to E- fuel mixtures

1998 ford expedtion running hot and will not hold antifreeze
A number of things. Check the hoses for cracks or leaks especially around thermostat housing. Look for green coloring. Also check radiator by looking underneath engine. Best way to check is by running the SUV. Make sure you put water in radiator and secure cap to pressurize the system. One other place to look for leaks is the overflow tank.

Hi speed miss over 50mph
On a Ford. bank 1 is on the side where cylinder #1 is and bank 2 is on the side where cylinder #1 isn't.
On the Expy, cylinder #1 is on the right bank, aka the passenger side.

How to test a ignition coil
There are two choices. One-take your vehicle to Advanced Auto or any other parts store and have them hook it up to their hand held tester that will tell you if anything is showing up as defective. If so, then you can replace them yourself. Second-Take it to the auto dealer and have them check it, but this way will cost you.

How can I repair my 1998 ford expedition's computer
Best thing to do is replace it. You can try getting one from a Pull-A-Part or junk yard reasonable or order one from a parts store but they are very expensive and you really need to know how to do it correctly. Otherwise you could damage other components. When it comes to car computers, the best advice is take it to your dealer and let them install it and reset it.
