why does my kia sound bad, and has trouble going past 45? on 2001 Kia Sportage

i was going to carbandale and half waay there it lost speed and began to sound bad. i put in fuel injection cleaner seemed to help alittle. but it still sounds bad . and runs rough. A week before my car wouldn't start and my son in law sprayed starter fluid in it to get it to start.

Do you have any check engine lights on? Sounds like an ignition or air/fuel mix issue. Usual causes: spark plugs or coils are bad. Or, fuel pressure/air mix. Need more info.

Check engine light flashing at you means the likely cause is a bad spark plug coil causing a misfire condition while driving. Go to a parts store like Autozone and they will give you a free read of the engine codes and then post on here.
