Quote from: daantjie on 04 March 2023, 08:05 PMDid you do anything to the fuel distributor? To my mind the only way you'll get revving up like that is with a corresponding open throttle situation so check throttle butterfly and also position of the air flap at the fuel distributor.

Quote from: Feather535 on 15 March 2023, 10:33 AMI found the cause of this problem, and it was totally unexpected. I disconnected the vacuum brake booster and plugged its port on the manifold, but the same thing happened: the engine started to race as soon as I took my foot off the brake. This was puzzling, because the booster should have been the only connection between the engine and the brakes--or so I thought. But then I realized that, on this car, there is another connection: cruise control. The cable that activates cruise control was slack, as it should be, when the engine isn't running, but I disconnected it, started the engine, and it didn't race.I didn't know the cruise control was even functional on this car and don't know why it was doing this, so the problem isn't exactly fixed. But with it disconnected, I can get back to working on other issues.
