Thread: stuttering at high rpm

Resistance checks are not 100% positive for coils. My fords coil was fine according to resistance, but it was still shot.

try a new ICM. That is the part that the coils sit on.

my moms done this and was the ecm the thing the coil packs sit on

well glad you found the issue
