First time posting on this site, but I always check here for info. You guys really know your stuff. Here's my probem: car is idling like crap. Changed plugs, cap and rotor. I still think it may be an ignition problem because suddenly my timing light is pulsing erratically (never had this happen before). Tearing into the distributor right now and have 3 maybe obvious questions but I'm not very experienced with distributors.
First, should the rotor be able to spin at all? It is tight in the cranking direction but I can spin it maybe an 1/8th of a turn the other way and lift it up about an 1/8th of an inch. It snaps right back when I let it go.
Second, when I spin the advance weights, the spring on one of them snaps it back into position right away but the other one gets stuck. Is this what is meant by the weights sticking or would sticking weights not move at all?
Lastly, how do I check if the vacuum advance canister is working? I thought that I could move the tab that it is attached to and stick my finger over the end to see if it stays.
Any help here would be appreciated. Thanks!
