I have a sniper coil I bought a couple of months ago and today for the 1st time decided to put it on and try it....it went nuts...vdi #'s jumping all over the place....constant chatter..... I haven't read anything about these coils being bad....anyone else have this problem with the small coil? I sent a email to Brad at Garrett's about sending it in but just wanted to know if anyone else has had this problem with these coils?
