1973 2.0 accelerations issues Options

[chrisf]

Hey guys,
I have a 1973 2.0 original injection system. The issue is this, from a stop the car nearly dies as it tries to accelerate. The only way is to rev the engine above 2,5k and slip the clutch. Once the car is above the 2,5k ish mark it drives great. It idles greats, it just does not accelerate like a dead spot. I checked the throttle switch adjustment as per the pelican instructions and one thing that I noticed was that when I turn it all the way ccw and then move it till I get zero, I get now resistance aka open at the full ccw and then when turning I get nothing till halfway and then i get a closed contact. It seems like there's no resistance just an open and close point? I'm thinking its the throttle switch and opening it to check it out?

Thanks for the help

I second a vacuum leak. Once you get above a certain RPM the leak is overcome by larger volume of air moving through the intake/system. Squeeze and bend all your hoses and look for rot. Check every clamp. I had the exact same performance issue on my Scirocco CIS injection. Between 2-3K it studdered. Above 3K it ran like a champ. Once I discovered the rotten hose it's never run better. It was slowly going bad over the years.
