any coil packs better than others?

[sbellxd00gt]

summit has some ford racing ones for $280, for a set of 8. they couldnt be that bad. i did start replacing them one at a time as they went bad, but after i replaced 2 and another one maybe more has gone bad i just want to replace them all and be done with it.

How do you guys know for sure which coil pack has gone out?

Should throw a misfire code. Get it scanned at autozone.

We have looked at all on the market and I can promise none are better that the OEM for perfomance or longevity

oops, but they look better then the oem's

MSD coils are some of the worst that I have ran into....

If its a dead coil - yes. If it's an intermittent coil that fires some of the time - maybe not. Maybe the later computers throw a code but on my wife's 2000 expedition i've had several coils fail and it only threw a code 1 time. Ford can look at the misfire data and figure out which coil it is, but that's a diagnostic charge.

The way i found figured out which coil was bad was that i looked at the voltage on the O2 sensors using an ODBII scan tool and figured out which bank it was on (on one side the voltage didn't switch). Then i replaced the coil on the front cylinder and looked at the O2 sensors again. I then took the coil i had removed and swapped it onto the next cylinder, and kept doing that until i saw the O2 sensor switching voltage again. Problem solved.

If It's missing bad enough or missing long enough it will set a code but Fords parameters for setting misfire codes is pretty wide, the best way to find on is Fords IDS system that can give a live power balance test.

I have had very good luck with the Accel ones
