Still engine stalling issues
Thanks much for all of the advice. Has been very helpful and have fixed some of the issues, but still not quite there. I'm sorry to ask for such basic advice, but would be grateful for some more assistance - helps me learn and keep the pontiac going.
I checked for manifold leaks (none), replaced all of the engine vacuum hoses and there were two that were really brittle and had cracks. The engine now idles ok - the vacuumn gauge is at about 16 in. hg when warmed up. The engine runs fine until put into gear, it then slows and stalls. Increased the idle, but did not make much difference and then when turn ignition off - diesels and knocks. Have to turn off in gear or knocks. Put idle back down where vacuum is at 15 in. hg on the vacuum gauge and it turns off ok without knocking, but will not run in gear. So now it is at a point where it will run at idle, but not in gear.
Dont know if makes difference or not, but plugged end leading to the vacuum advance at the distributor to disconnect, car ran the same.
Anything else to check?
