I got the car as a project with a bad head gasket, when I got it I turned it on at it had a surging idle but I didn't think of anything since it had a bad head gasket anyway. The car is a 1984 325e
I replaced the head with a rebuilt 323i head, 325i intake manifold, 325i throttle body, replaced the head gasket, water pump, timing belt and timing belt tensioner. I finished installing everything today, turned the car on and it still has a surging idle.
What could be causing the surging idle?
Here is a video of the problem
