    I have same problem with my 2004 Kia Optima. This just started last week. While driving the engine seems to lose power and then jerks back into speed, then repeats about every 10 seconds or so. Worse jerking when driving the streets at lower speeds. I checked the air filter but that's ok. Maybe dirty fuel or fuel jets need to be cleaned, something that I can do? It's the V-6 engine.

04 kia optima 2.7 V6 changed out altenator and


Don't think changing either the belt or the alternation would cause those changes. You must have moved or damaged something else in the process. Just what, I have no clue.

Sound like you either had to disconnect a wire to get out of the way when you removed the altinator and didn't reconnect or you knocked one off go back and check your work.
