Hey guys, newbie to kias here,

I have a misfire on Cylinder #3, it runs fine until it warms up and starts missing pretty bad, expecially when the engine is under a load accelerating or up a hill.

Looking at the front of the engine, how do the number go? 1 2 3 4 with timing belt by #1? I checked the plugs and the #1 (closest to the timing belt) seems to be dirty and missing spark. But why would the engine code say #3?

Thanks, and also intersted to hear about the debate of Electrical or Fuel Delivery problem.
