As title implies, I'm hoping to try and solve my idle problems. Currently everything is pointing at ecm, so hoping I can try someone's spare/main if someone would be so kind. If cheap enough ill even buy.

99 4x4 TRD 6cyl MT non-cali emissions w/ ac and ps.

Toyoda pt 89661‑04450

Located in Peoria but willing to travel.

The problem: high idle. Followed diag from fsm. IAC valve new, and confirmed working. Wiring conformed OK. However ecu is sending both open and close signal to iac at same time. Believed ecm error. However ecm tests OK with ohm-meter. All that leaves is ecm :(
