1986 Toyota pick-up with a 22RE, when the motor is warmed up the idle drops down around 600 RPM and idles rough the truck runs fine and drives fine just idles kinda funny. i have done the cap/rotor/plugs/wires and the motor has over 230000 miles. Its been acting up for a couple of months now. just curious if anybody knows of any idle sensors or some emissions sensor that could be causing this problem. oh i have check all my vacuum hoses and the all seem fine. thanks for anything in advance
