hi.

i am wondering if my issue is with my coilpack unit, subaru wagon r plate.
ticks over fine, drives fine, but now and then driving her you get a feel of a slight miss or a lack of power or something as it feels a little jerkey at times upon driving steady speeds etc, what does anyone else think. changed spark plugs and leads and looked ok ,apart from new fuel pump may be the issue and where is it located> do they give issues with running, the maf sensor i unplug and the engine stalls as ait should so presume this is working all ok? or am i mistaken?
thanks.
