Re: Phantom fluttering

To try to clarify.
This fluttering at hi way speeds is not a new issue. I first thought is was caused by plug wires: new wires, still there.
Maybe electronic control module, no. It won't run at all if faulty.
Maybe fuel pressure: I installed a new fuel pump and regulator. Still there
Maybe a lean condition: I changed the metering rods and springs. This helped with the hesitation at low rpm, but not the "at.speed" issue.
Do I look toward the transmission?
