Intermitent spark on 4 cylinders 1996 olds aurora

The firing order is:

1-2-7-3-4-5-6-8

From the left (front) bank of cylinders are number 2-4-6-8 and the right (rear) bank cylinders are 1-3-5-7. Engine firing order is 1-2-7-3-4-5-6-8.

Hi. You have misfires on cylinders 4, 5 and 6. If there are no faults on cylinder 1, 2 and 3 then I would check the power to the left bank injectors. Also check spark plugs and ht leads. If there are running issues then this should be an easy fix. If the faults are very intermitant then it can be a bit tricky to isolate.

You might find the firing order is cast into the manifold a lot of the oldsmobiles had this!

The starter motor sits in the "valley" between the two bank of cylinders underneath the intake manifold.
