Question about 2004 Kia Sorento
Could be a number of things but it is most likely the fuel injector or the computer? Any know problems?
If it is a misfire, then that means it is probably the plug or the wire, change those first, if not then yes check the injector.

My 2004 Sorento 3.5 had the same problem, dead #5 cylinder. Replaced plugs, coil pack, wires, computer $$$ and still dead and would hardly pull itself. Would backfire some when trying to drive and no power. would only give a code for dead #5 cylinder. Two very good shops and one very bad dealership and hundreds of dollars later, still nothing. I took the car home and took the front of the engine off and found the timing belt tensioner was stuck and over time had allowed enough slack in the timing belt to slip one "cog" on the crankshaft. This could not be found with the codes and was only found by taking it down to the belt and checking the cams and crankshaft timing. Not a job for the faint of heart. Lots of work on this type of job. Hydraulic tensioner had just stuck and wouldn't keep the timing belt tight enough. The tensioner looked good on the outside (no leaks) but when put in my vise to reset, we found it would not return to the extended position. This is not common but I have found several people with this type of symptom with little or no solution found on-line. The dealer said the cylinder was dead and the engine would have to be rebuilt to the tune of almost $3000. NOT!!! If all tests have not found a cause, you may wish to invest in a new timing belt tensioner, timing belt and water pump.
