About a month ago had car dynoed an it had a small " blip " on dyno ...my tuner said maybe plugs or coil ..it was a small slight hesitation ...
So tonight I pulled the old plugs TR7s and installed TR6s (place I bought them from said the cobra calls for TR6s)
I installed them tonight and now getting a misfire on #8 so I swapped coils with another cylinder to see if problem went to that cylinder and it did not stayed on 8 ...I even put one of the old tr7s in to see if problem went away same thing ...car runs like shit under boost
I ran a snap on scanner on the car driving it around and watching the scanner out for a ride #8 was showing -39 on the graph....
So I'm lost here on where to go ...
