The fuel regulater diaphragm is bad, fix it.
If the motor is rebuilt I think that maybe a sensor wasnt connected
You need to clear the codes with a engine scanner.
If it has one, it would be inside the distributor, so the distributor would have to be removed and rebuilt, or replaced. Check the warranty first on your vehicle.
if 4,6L Color is usually yellow or red egr - under manifold in rear O2 - rear back in axhaust manifold
You need to grease the cable that runs from the speedometer to the trans. (Best to use white lube)
Faulty sensor get it replaced if not check to make sure wire isn't shorting out
No, the sensor will need replaced.
NO. there 2 different things / sensors.
There are two separate sensors that play here. the "coolant temperature sensor" and "coolant LEVEL sensor". I suggest confirming which of these was replaced, as it is very common for them to be confused. likely you will find the coolant sensor that was replaced was the one on the engine (temperature); The LEVEL sensor is mounted either in the coolant resivoir or in the radiator. Probably just need the proper sensor replaced.
You can't. You either replace it or get it rebuilt.
The Intake Air Temp sensor is integral to the Mass Airflow Sensor (MAF). It cannot be replaced seperately. The MAF sensor would need to be replaced if you are trying to replace the IAT sensor. - TechJK -----------------------------------
Only if the sensor is malfunctioning.
