Hello, Yesterday I had a problem that sounded like it could only be the cold start valve. So, I replaced it today. Now I seem to have a different problem in the same area. My timing is a little high at 45 @
3000rpm with full vacuum, so I'm going to drop it a hair, shooting for 42. After replacing the cold start valve, I still had a high idle (about 2,000rpm). I started to adjust the idle down and I was just 1/2 turn from all the way in. So, I started backing it out. As soon as I did that, it started surging... 1 sec at 2,000rpm, 1 sec at 500rpm... on and on.Any ideas on what might cause this? Thanks in advance, Tim
