Question about 1998 Ford F250 SuperCab
Have a 1998 Ford Motorhome with a fuel injected 460 engine. on highway speeds after about 20 minutes the engine light turn on and off on a 2-3 minute interval and then stays solid on. Once you turn the engine off or slow down to street speed the light does not come on. have checked all fluids check the fuel cap what else can I check, try to plug into the computer port although I do not believe there is one, prior to ODBI engine? any assistance would be appreciated.
Plug the computer on to the port located under the dash on the drivers side to get a code reading. It sounds like a 02 sensor about to go bad. If you get a 700 area code, its a transmission sensor code.

SOURCE: 460 motorhome fan belt slipping
Check and see if the pulleys are shiny looking, also are the batteries low on charge, if you have more than one battery the load on the alt is huge, add in a low or bad set of batteries and then the belt can deliver enough power to spin the alternator, and it slips. Worked on motorhomes for year's, saw this allot.

Check to make sure the fuel pump is working. On the fuel rail there is a test port that you can connect a mechanical gage too. Also there is a fuel cut out switch under the dash closer to the floor that has a reset button on it. If you hit a very hard bump it can trigger the cut out switch. It is designed so that upon impact in a collision it cuts the fuel supply to the engine to prevent an engine fire from leaking fuel. Sometimes these switches go bad, But, try the reset first and be sure to check that the fuel pump is working.

it might have just run low on fluid while driving,the front seal may not have been installed correctly,or the cooler lines or cooler might be plugged causing the trans to overheat which will cause it to leak a steady stream...for example,my 94 bronco with a e40d acted like that too when i worked it really hard pulling stumps out in the summer last year,it leaked out really bad until it cooled down,i put 20,000 miles on it since and it doesnt leak not even a drop.so mine was just overheated really bad.As for if it is the same between vehicles it is only if both trucks are a big block,and if both are 2wd.
