Car was running great. Hadn't been tunned up in 10 years. Decided it was time and replaced the plugs, wires, dist. cap, rotor and serpentine belt all as a precaution. Now it idle's rough then stalls. Checked all the wires and plugs for spark and even put back the old plugs, still no good. Sounds like I unknowingly disconnected some vacuum hose or wire?.
Any idea's on tracing the problem?
