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.

new gm pump one year ago and fuel filter a momnth ago. no it just feels like the ignition shuts down. never thought fuel delivery problem because of the backfiring

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
