Question about Ford Fairmont
Have them change the knock sensor. What this sensor does, is sense preignition and ****** the timing when predetonation is detected. If the sensor is keeping the ignition retarded, you will have lack of power, poor transmission shifting(a lot of times a trans can be mis diagnosed due to a driveability malfunction). What he will see on the scanner is timing that will either not change or change very little. If you can hear knocking while accelerating(even standing still) this is a good indication. You are correct, that is high consumption. One thing you can do for yourself is, whilst driving at around 60 kms, step on the accelerator and listen very closley for an almost metallic pinging coming from the engine bay. This is a great confirmation and you will be able to instruct your mechanic what to change. Let me know and I will continue to assist.
