Hi Guys,

158K miles on her now, I had swapped out the OEM coil for a MSD coil at 100k miles when I did the plugs and wires too (OEM coil was working fine, some rust on the #3 coil lead). Well, 58K miles later......I lost all power above 1/2 throttle (sputter with zero acceleration) and got a P0303 code (mis-fire #3). I swapped plugs around and still got the P0303 code. I put in old OEM coil, took her for a run, and everything seems good now.

Has anybody had the MSD coil fail on them?????.......Is there a better coil than the MSD or OEM coil?. I like the brass leads on the MSD but don't want to put a new one in every 58K miles.

Thanks.......

 

Nice....I had a Screamin Demon CP do same thing last year with about 43K miles on it.....so this year I went for MSD CP and MSD Wires.....lol.

 

Hahahaha well, hopefully you get more outta it then i did. I am running the Iridium IX plugs too. I had to drill out the mounting holes o the MSD to get the OEM bolt to fit. Did you have the same problem?

 

Stock one is best overall.

 

No drilling...

Harware stores around here well stocked with ss bolts, washers and even new rubber o rings....

I have heard where some use a dremmel tool to remove the OEM bolts outer sleeves.
