Hey Guys 256k King Ranch HD tow 5.4 EL 2014
I'm getting a pulsing shudder if i feather the throttle to accelerate a little .. if i push harder it will downshift ok and run smooth .. I'm thinking injector? coil pack but fear trans issue ( have changed trans fluid and installed drain plug in pan for servicing the no service reqd trans)
I did try to goad it into behaving worse and managed to get a flashing CEL but it cleared
thoughts??
