Thanks, Steve.
Yes, I've tried pressing on the gas before starting, and even cycling the key a couple of times to cycle the fuel pump. Motor jumps to life, but then immediately chuga-chuga. If you hold the pedal down a bit, it struggles to
rev while chugging, then clears up and all is good. More throttle makes the chug cycle shorter, but it's still that "running on 3 cylinders" feeling for a few seconds.

Really more annoying than anything. I really hate it when someone gets in my car and starts raving about how perfect and beautifully maintained it is, then I fire it up and it goes CHUGA-CHUGA. Kinda like finding out that beautiful blonde next door has bad breath.
