I purchased the car about 3 month ago. It supposedly has 78,000 original miles. It sat without being ran for 2 years because the owner lost the key. I had another key ordered and got a new battery. The car started right up and ran very smoothly. I did the basic things like replace the plugs, wires, ditr. cap, rotor and air filter. The engine still seems to run very rich and idles eratically. Does anyone have any suggestions on how to adjust the fuel mixture or idle ?? It did idle fast at first but there were a few disconnected vacuum hoses. I hooked them up and now it idles to low and almost stalls.
