So i've read around but not getting a straight answer, I'm believing it's CAS but coming here for a second opinion
So occasionally the engine will "hiccup". ill be driving down the road (usually I only notice it during freeway driving) and then the engine will like die for a short period of time, (it feels like when you lift your foot off the pedal for a split second)
I think I read somewhere it was CAS but can't since find that page to read up on it.
any help / confirmation / ways to troubleshoot it? Compression is good: 142, 150, 145, 145, 150, 150. New o2 and cleaned AFM.
is running a Power FC
RB20DET 1992 SKyline r32
Thanks for the help guys!
