Will a car with too much oil in it overheat at speed but run well at normal 60 km speeds

If you want to know about this model I suggest you visit the Wikipedia page below.

https://en.wikipedia.org/wiki/Fiat_128

1962 Ford Taunus 17 M 60 hp: The maximum speed is 135 km/h (85 mph)
1976 Ford Mustang 100 hp: The maximum speed is 173 km/h (107.5 mph)
1978 Ford Fiesta 66 hp: The maximum speed is 145 km/h (90 mph)
1978 Ford Capri 107 hp: The maximum speed is 186 km/h (115.58 mph)

Please note that these speeds are approximate and can vary based on factors such as the car's condition and modifications

To reset the tire pressure system, do the following:

(NOTE!....Do not reset the check tire pressure system without first
correcting the cause of the problem and checking
and adjusting the pressure in all four tires. If you reset
the system when the tire pressures are incorrect,
the check tire pressure system will not work properly
and may not alert you when a tire is low or high.)

1. With the engine off, turn the ignition to ON.
2. Press the MODE button until the DIC reads LOW
TIRE PRESSURE HOLD SET TO RESET.
3. Press and hold the SET button until you hear a
chime, and TIRE PRESSURE RESET is displayed.

You will hear three chimes, then the LOW TIRE
PRESSURE message will go off and the DIC will return
to TIRE PRESSURE NORMAL. If the LOW TIRE
PRESSURE message comes back on, the check tire
pressure system has not reset. Repeat the procedure.
The system completes the calibration process during
driving. The system learns the pressure at each tire
throughout the operating speed range of your vehicle.
The system normally takes between 30 and 60 minutes of
driving to learn the tire pressures. The system normally
takes 10 to 20 minutes of driving in each speed range to
learn tire pressures. The speed ranges are 20 to 40 mph
(32 to 64 km/h), 40 to 60 mph (64 to 96 km/h), and above
60 mph (96 km/h). This time may be longer depending on
your individual driving habits. The learning process does
not need to be completed during a single trip. Once
learned, the system will remember the tire pressure until
the system is reset.

TPS (Throttle posision sensor) would be my guess

Please specify the fault in detail as it is not clear. Did you refer to poor acceleration.? If so check the fuel pump and ignition system.

Ask an Alignment Shop to look up the specs

You are leaking coolant somewhere. Are there any wet spots on the ground when the problem occurs?

Not normal, clean burning engine, mine has 220,000 kms's. Are you using a full synthetic oil? Tried it a couple times and it took 1 litre between oil changes. I use semi synthetic oil, no issues. How long has it been burning this amount of oil? Get to your dealer and have him fix your engine.

You have oil leaks getting on the exhaust system, they are getting into the car, have the car checked over to find source of leaks.
