I sometimes almost stall the the car, or as it is catching, it revs up too quickly and burns the clutch. I feel like an idiot teenage who can't get a clutch right. Maybe that's how VVT system behaves and I just need more time to get used to it?? I'd driven it around for over 2 months straight after I got a good fuel pump in and that wasn't enough to get completely used to it. It's been in the body shop for a week or so and I've been driving the 74 GTV with the Norman head and Ingram euro cam, and while not more powerful, the launch is so linear that I felt so comfortable, like putting on an old glove.

You don't mean perhaps that if you just touch the trottle and let go, the revs tend not to drop away straight away, but infact hold for a moment then fall? I had a thread in the 75/milano section however no one seemed to know anything about it, as theres a lot of US guys and i dont think they ever saw TS's. I thought it was some anti-stall device.
Anyway my point was mine does this and i find it hard to take of smoothly as well and takes a while to get used to rev matching. I unpluged the connector on the 'air bypass valve' (Well thats what I call it, I dont know the real name for it, but its plugged into the engine side of the plenum) and this stops the 'rev holding' but makes it run like sh*t, hunting and carrying on like a pork chop. I am yet to find a way to stop it (ecu).
Has anyone else noticed this with a stock motronic transplant?
