Misfirin or fuel problem???? - Willow1983 - 13-09-2014
Hi people, I hope u can help me, I have a 306 xsi s reg. for just over a week my car seems to be misfiring at low revs about 2000rpm ish and only really notice it in 2nd gear. After this it seems to pull well. I've also noticed when starting it will fire up as normal ( meaning a couple of turns and it fires) but it seems like it doesn't reach idle smoothly. Hope this makes sense
I've changed the plugs so far and was going to change the coil pack next but thought I would ask on here first. Thanks for help

Could well be the coilpack yes.
Just go through the sensors one by one, not sure if it's the same on xu engines, but certainly on tu engines the map sensor is usually the culprit for causing problems similar to this
