If idle is low, I would not suspect vacuum leaks. Also, pot problems usually cause the EHA and ICV to ramp idle up, then down. Make sure throttle linkage is allowing a return to idle - if pushing linkage to rest stop causes idle to increase, look there for problem.

See if unplugging connector to ICV changes the idle. If not, then likely you have no ECU function. Check the OVP relay and fuse.
