I was wondering for you guys that have the 4.6L Stroker what grade of gas are you using. My compression ratio on my stroker is 9.5.1
and I was using 87 octane. I have been having a misfire at idle and at low rpm and I have looked, tested and replaced almost everything. Guys could it be the 87 octane, do these motors pre ignight the fuel due to the higher compression and cause it to misfire. Today a filled up with 91 octane to see if it would make a difference. It is a little too early to tell because I still had 1\2 a tank of 87. What do you guys think of this.
