we humans need to breath so dose cars their air filter is our lungs.
Your car can run sluggish and have problems starting
its near the front of car u need to get under ur car to find it
Depending on how the car is used and the location is very important for this. A car in the city may need a new filter every year or 15,000-30,000 miles. A car in the country will need one less often.
If the diesel fuel "gels" then yes the filter will need replaced.
I have never seen a car that did not require a fuel filter of some sort, and they need changing from time to time.
no you may need a transmission adjustment or maybe a new filter
it could be a fuel filter maybe the one in your car is old and you need a new one
Yes, there is always dirt in the air.
the oil filter's location varies from car to car. It's often accessible only from underneath, and may be shielded by the undertray which will need to be removed first. On some cars the filter can be accessed from above.
My car starts and runs fine .Yours may need a fuel filter or pump.
NO! It should not be running.
