it sounds like you need a new coil pack Or you could have two of the plug leads reversed. I'd check and make sure I have voltage at all 4 plugs before I bought a coil pack.

Why are only 6 of 8 cylinders firing on my 1996 ford thunderbird V8?
If you are aware of which two cylinders are NOT firing, I would change out the spark plug wires and the spark plugs with brand new for those two cylinders. If you aren't sure which cylinders AREN'T firing, then do a complete change of new wires and spark plugs. HINT: Try not to use Bosch plugs... I did, and had all kinds of trouble with them even tho they were inexpensive and supposed to be just as good.
