Misfiring 2.5

Post by S6Z4 » Sun Jun 23, 2019 11:17 am

Hi I’ve started get a misfire on my 04 2.5
Looks like I’ll be changing the coil packs and plugs on all cylinders just to be safe there all done.
What recommendations has anyone got for both ? Tia

Are you getting any error codes?

Change the plugs first. NGK or Bosch probably.

Usually with Coil Packs it's only one that goes so instead of changing them all narrow it down to which one is failing and replace it (if it is a faulty coil pack).
