right on I been reading a lot of misfire issues in forums and many said they
replaced every dam coil - plugs and wires with no result I am going to try
and hunt down a new ICM
Thanks to gweg_b, and Justin85

Hey Justin,

Can you show me where the ICM is located?
After reading another guy's post it may be just the issue I am having?
I am thinking now maybe I should start there first.

Aloha Justin85,

well the wires are all in the correct position from the previous owner.
I was surprised - I was actually hoping they were out of order so it may fix the problem.
I also made sure no wires were touching or near the O2 sensor - none were but were close

Will write back with results

Aloha from Hawaii

Thanks crash93ssei,

I will remove and inspect plugs and wires - you mentioned plug brand - is this crucial for the Bonneville 3.8?
There are several companies to choose from - can you please recommend a brand that is/was good for you?

Thanks again!

Can anyone help diagnose a misfire I am having with my 2004 Bonneville with the 3.8L?

I just bought the car with 144k on it.
I was told by the owner all maintenance was done regularly and the car is still solid and drives nice and tight.
The previous owner told me he had replaced "One" of the 3 ...
