I just replaced head gaskets and plugs, and coils. Now for some reason it has a hesitation when accelerating, plus idles rough when warms up. Im gettin codes for the primary/secondary coils, and misfire reading. But plugs and coils are new. All vaccums are hooked up and everythings plugged back in. Its got me totally puzzled. Its the 4.7
