On the ign. Module, hard to screw up. Those plugs are a positive fit.

Here are the current symptoms-
I put some fresh plugs in today, the old plugs looked ok, but it looked like they were running a little lean.
Starts immediately with very little cranking. Normal driving is smooth, up to about 4K then it starts to break up, cutting out, missing repeatedly.
Although if you can gradually build revs it’s very smooth, but If you put the hammer down, at any rpm it will break up and miss like mad. So far, no check engine light, no codes have been set.

We’re going to start looking at sensors next.
