Do you have a leak in the brake booster diaphram? The brake booster draws it's vacuum from the #4 intake. There should be a one-way valve screwed into the manifold. Check that as well.
1976 spider braking issue
Hello , I have a 1976 Alpha Spider , just recently I noticed that when I brake my car tends to accelerate, this happens when comming to a stop and the car is in neutral, the harder I press the brake , the more it accelerates. The brakes are working fine , no issues or any diference in pressure when I brake. Could you help identify what can be causing this issue . Thanks
