I did a search but could not find anything that mimics my problem. Please direct me to an old thread if you know where this has been discussed in the past............
I have a '93 5 speed SC (approx 107k on the odometer). We just drove it about 350 miles round trip to the the Carlisle All Ford meet. It got FANTASTIC gas mileage, even with the 3.73 gears and taching 2200 RPM on the highway.
However, at sustained highway speeds, the check engine light would come on. When we'd stop at a WaWa for a coffee and start it up again, the light would be out. Then, once on the highway again, the CEL would come back on in about 15 miles of travel. It never comes on when I'm driving in the city.
Sometimes, at low speeds, when turning around in a driveway or parking lot, the RPMs drop so much that I pretty much loose the power steering, but the engine never stalls.
Recent Repairs include (within last 10k miles):
new motorcraft coil pack, motorcraft wires, motorcraft plugs, clutch, motor mounts, trans mount, motorcraft Crankshaft position sensor, motorcraft camshaft position sensor, motorcraft water pump, all new motorcraft belts
Thanks for your time!
