So, before I changed my head gasket, the way it used to run was when you got in and started it, it would idle up to about 1200 to 1500 rpm and then come down to about 7 or 800 after warming up. After I got the head gasket changed and put back together, it idles up to about 1500 and stays there. Is something not functioning properly? And even odder is when I'm turning and got the clutch in moving down a gear as I'm slowing, it will idle up and down likes theres a vaccum leak. I've checked all my hoses and they are all on. I suppose I could have a puncture in one but I don't know how it could be from when I'm slowing down and turning cause it doesn't happen when the car is at a stop. So I decided to experiment with the distributor. I know there is advanced and retarded. If we are looking at the driver side of the engine facing the distributor, I am going to assume that having it turned as far clockwise is advanced. Thats just the position I've always had it. When I decided to move it counter clock wise all the way, it started up and ran right at 700 rpm without having to come down. However, the car was even more of a wimp than it already is so I will assume that is retarded. Why would that bring the rpm level down? And I also don't hear it idling while in turns with the clutch in. Should the distributor be centered? I was told advancing the timing once the car is hot, it won't start but like I said, the timing has always been advanced and started fine.
