Had a mistake of putting the wrong individual pigtails of our car's IACV wirings, and it somehow burned the resistor on the ECU. Now when it's not on a normal temp, the idle is down, but when it's in a normal temp, it goes higher. Which is the opposite. Can I rev the engine to make the idle higher for it to warm up faster? While I save up to fix the ECU?
We have an old 97 Toyota Corona M/T clunker.
Thanks!
It's operating backwards? If that's a 3 wire connector the middle wire is 12 volts.
It sounds like you have the 2 outer wires reversed.
Check to make sure you have around 12 volts (+ or - 2 volts) to the middle terminal. (Key ON)
If you do, try swapping the 2 wires on the connector's outer terminals.
That will reverse what's happening now
Thank you Jack! Appreciate this.
But I'm afraid the ECU's IACV capacitor is shot, I'm now running the car with the IACV's pigtails disconnected.
