BUICK PARK AVENUE SPARK PROBLEM

1999 Buick Park Avenue • 177,000 miles

How to get spark on cylinders 1& 4?
No spark on cylinders 1& 4. The wires and plugs were tested and are OK. Then scanner says multiple misses PO300. 3.8L.

Swap the first coil with the second one and see if the miss moves to different cylinders. If it does, change the coil. If it doesn't, change the ignition module.
