Thread: Time to replace coils packs on Thor

Tools used

The only other part I removed was the plug lead clamp which allows a lot better access to reach behind

There was some corrosion on the bolts where they poke out the bracket so I sprayed some crc behind the bracket onto the bolt ends to help remove them easier.

Then removed the two top bolts of the drivers side coil pack and removed the coil pack. This allows access to the lower bolt of the passengers side coil pack, then remove the top bolts and it's off.

Pic with drivers side coil pack already removed.

This is what they looked like.

Wire brushed the bolt ends, and cleaned up the spark plug lead ends as they were 2 years old.

Assembly is the reverse of removal.

It took three hours and I was in no rush, I'm sure if I was to do it again I could do it in 1.5 hours.

Making sure the plug leads were pressed on properly took some time, one particularly gave me a hard time.

She's now idling a lot smoother.

Glad you got it sorted, nice work!
Was it missing all the time, or just under load?
I'm trying to work out what is causing mine to hesitate under load between 60-80 kmh. I changed the MAF a while back which did help a bit, but my coil packs would be the original ones 15 years old now, these things don't last forever.

Hi Peter,

I noticed it missing on my last trip in October, which sounded like maybe just one cylinder and it was a little rough at idle. I didn't notice anything while driving.

I only took it for a few short drives since then, and the miss became very noticeable at idle and very rough almost as if it might stall. I'd say at least 2 cylinders were missing, with slight acceleration it improved but it was noticeable while driving but I didn't go above 60ks around town.
