Hello, I'm a newbie here. Just bought my first Toyota ever, a 1985 pickup with 146K miles. The engine starts readily and pulls well. The idle is smooth, but that's the problem. The truck failed state inspection today because the idle is too high. How does one adjust the idle? I don't see any idle stop screw or idle mixture screws. All the vacuum hoses look good... no cracks, no breaks, nothing mysteriously disconnected or blocked off. Please advise.
