Ford 460 Problems

I just spoke with a friend with a 97 Pace Arrow with a 460 Ford engine. In his last 20 miles of today's run a couple of things happened. Twice the speedometer and tach cycled from normal readings down to zero then back to normal readings. Also on another occasion, The engine "coughed" as if the ignition was turned off and back on instantly. So the speedo & tach cycled twice and the engine coughed once, then ran smooth. Any ideas???? He is parked till after the 4th, but concerned about hitting the road not knowing what to expect. For those of you who have or have had a Ford 460 in a Fleetwood, where is the OBD or DLC to plug a scanner into to check for codes???

That is not an OBDII engine, but rather a Ford EECIV system. It has a connector that you either use a device that flashes, beeps or a fancy one counts and generates codes. Poor folks like me use an analog multimeter to count the pulses of the system codes. No idea where it is located. On my '91 Ranger pickup and Dad's old '84 LTD (long gone now) the connector is in the RH side of the engine compartment near the battery, no idea where it is on a chassis like yours.

You need a manual to tell you what the codes mean.

I drove 460 trucks for years. Sounds like an ignition switch issue. I would check there first. We replaced several over the years. Combined, I worked at and then owned a Ford Dealership for 26 years. I'm not a tech by any means, lol.

I always check the ground strap in the steering column for ware as it can cause a lot of problems

Go to this post link below and scroll down to the last two messages to see the proper code reader and typical convection location.
