Can't get over 100 mph :( the rpm needle just jumps back and forth as the engine is cutting out. Figure it's the coils or sparkplug wires... secondarys tested out to be 18.6k and thats out of spec so could that be causing this? primariys are within sec tho. Already swapped v reg and icu to make sure it wasntthem.
Just curious on what some peoples thoughts would be.. I'm buying new coils tommorrow to be safe tho.
it cuts out at around 8k rpm as well... under hard acceleration
has 12k miles
