It is also a good idea to check that the distributor is correctly timed... Having had problems due to a distributor being timed 1 plug out so each position was rotated by one...

The distributor cap will have cylinder numbers on it.

Cylinders #1, #3, and #5 are on the left side (drivers). Cylinders #2, #4, and #6 are on the right side.
Cylinders #1 and #2 will be in the front of the engine. Cylinders #5 and #6 are in the rear of the engine.

Be careful, as #3 and #1 will not be where you expect - #1 will be in between #3 and #5 on the distributor.
