Fuel injector?, wire? manifold leak?
If cylinder one is misfiring on the Kia Sportage 2.0 it could be that the spark plug in that cylinder needs to be changed. It can also mean that the piston in that cylinder is sticking.
If you have changed all the Plugs, wires and coil pak then look at the fuel injector on that cylinder. Might be a good idea to replace them all. Should clear it up. My 99 B3000 had the same problem. The key was my fuel comsumption. As long as I held the RPM's above 2000, it ran fine. Ideling was a little shakey.
it depends on what kind of 6 cylinder but it can be the module the coil packs or the distributor It's on a '96 V-6 Pontiac Firebird. I'm thinking it could involve the ECM or an injector could not be pulsing. But how do I check and fix both?? I changed my coils on my 98' Camaro three times, they run about $35.00, the number 5 and 6 cylinder coil should be the last one when looking under the hood right over the right valvecover.
have misfire on #5 on a ford f150 4.6. changed spark plug and coil pack and injector.
You need to check compression on #6.
Low compression in a cylinder, a burnt valve, loose plug or plug wire, bad injector, bad electronics.
The plug, wire or coil could be the problem. Usually if the injector is failing you will get different codes. I just replaced plugs and wires from a 2002 and they were in very bad condition. The van had 90,000 or so miles on it. When these were changed it ran like a new van. The back three plugs were just awesome. (sarcastic) That is another issue though. Good luck.

check the coil pack
You may have a bad fuel injector. Try to single out which cylinder is dead, then remove that spark plug, if the plug is clean and dry you have a faulty fuel injector.
Check your TPS and O2 sensors. Could be a bad thermostat. My 94 did that ,changed it and solved problem.
Run a compression test before you spend too much time checking out other potential problems. If the compression tests good, try swapping the fuel injector with a good cylinder and see if the dead cylinder moves.
im having the same problem its a goofy cylinder.......im guessing you changed plugs wires and cap.......make sure wires are routed correctly......other than that im thinking its the injector
Theres three coil packs; one fires two cylinders. I suppose if one is bad then it could cause the two corresponding to misfire. I had one cylinder misfire, it turned out to be the fuel injector.
It is feeling silly and my other answer is it is behaving badly
most likely cause is #4 coil. later models all have individual coils for each cylander a mechanic can check it pretty quick quick for you
could very well be the injector. could also be the distributer or the plug lead
Each 90000 miles.
Yes but it wouldn't run very well
this is most likely a bad injector. Try a tank of premium gas and Lucas injector cleaner. If it still misses, you probably need to change an injector.
check cap and rotor..... check valve clearance "cold"
Spark plug wires? Coil pack? Dirty injector? Spark plug wires? Coil pack? Dirty injector? Spark plug wires? Coil pack? Dirty injector?
Sensor??? A misfire is usually caused by spark plugs and wires. After that you change distributor cap(if equipped) , fuel injectors, check for proper compression.
The 4 cylinder has a timing chain that does not require replacement and is designed to last the life of the engine.
