Hi Guys,

I have a 2004 X Type 3.0 Auto.

This morning the car started misfiring when in idle, but only when the AC is on. There's a slight stutter on acceleration but as soon as I turn the AC off it goes away.

I've recently replaced spark plugs and MAF sensor. Coils seem fine.

Any typical things I could look at? Did some googling but there seems to be a thousand causes for this.

Thanks in advance!

Sean
