Just got my engine started back up and it seems to be really lumpy, its just a rebuild but something isn't right, its almost like its not running on all 4 cylinders and it makes a distinct little pop sound every now and again...

Here is a video to help out, anyone got any definite ideas to what could be wrong? Bare in mind i've left it idling for 2 - 3 mins as i thought it might be the ECU calibrating but no change as of yet..

Each cylinder has a spark, each cylinder has compression. Cylinders 1 and 3 are working, cylinders 2 and 4 are not...
