How Can You Tell if a COP is BAD?
[sm=helpout.gif] How can you tell if you have a bad coil on plug? In the past I have stuck a new one in the holes until I found where it smoothed things out. What happens if you have 2 bad? This method won't cut it. Is there a tester?

Kind of a bogging feeling...it will feel like your only running on 7 cylinders...tough to explain...

You will get a Check engine light if one goes bad. I also imagine it would be pretty obvious as one cylinder would just stop working.

NO YOU WILL NOT GET A CODE 70% of the time till the car does not want to run
Have it put on Oasis at Ford, you may have several issues, . Had a 4.6 with 4 bad Cops and it idled wierd and miss every now and then.
No codes, Oasis will test each one and monitor the system, way better than the ECM can do its own self[:-]
if you have a bad cop, I have 8 Excellent ones from Ford. What we do is repalce all eight under warranty and keep the good ones to ourselves, in this guy case, his misfire were the garbage platinums in the motor and not the COP'S, so I have 8 of em with 10k on them, still smells brand new from an 2002 4.6
