Vacuum leak?
check that the O ring was replaced when oil filter was changed. id O ring is good and filter is tight, and housing still leaking, replace filter housing
If the diesel fuel "gels" then yes the filter will need replaced.
A dirty air filter can cause your engine to stall out, or only run at higher rpm's. Try changing the air filter to see if the problem clears up.
Yes (, just be sure the engine is not running) .
You do not need a photo. Just follow the fuel lines from the fuel tank to the engine and you will find the filter. If you find no filter then the filter is a permanent filter inside the fuel tank that is replaced when the fuel pump is replaced.
No it would not as it is for emissions only and has nothing to do with engine running. If you have a problem then you will need to have the engine scanned for codes and diagnosed. That should fix your running problem. If you have not replaced the fuel filter in the last 2 years or 30,000 miles then that should help the situation.
A clogged or defective fuel filter will very likely cause a check engine light. If it is suspected, it should be replaced.
Not a problem unless you plan on running the engine... Of course it is a problem. An oil filter is mandatory for the life of the engine.
They are both very important. But a clogged fuel filter will stop the engine from even running. A clogged air filter will hurt performance and mileage but will not stop the engine from running unless it is totally clogged. Replace the air filter every 30,000 miles and the fuel filter every 50,000 miles.
every 3,000 same as oil
The oil filter on the Kia Sportage is found on the driver's side of the engine. The oil filter should be replaced during an oil change.
Yes , although you will have to top up the engine oil level ( or prefill the new engine oil filter ) * assuming you haven't put the required amount of oil in the engine already *
