There could be a re-learn procedure to implement to restore idle speed.

The car is a 1600cc automatic transmission e trottle model.
I cleaned it because on inspection there was a tacky/gummy substance around the butterfly.

I took the air filter hose assembly off the throttle body and removed the four bolts out, removed the throttle body and spray the interior with a icf aerosol cleaner and reassembled.

If you unplugged it you will have to perform a re-learn procedure. Is the CEL on?

Please read all instructions and be familiar with them before any attempts.
A stop watch or an analog clock with a second s needle will be useful.

ECU Resetting Procedures

Timing is extremely critical. If it is NOT DONE within the specify time, the ECU will not reset and the Check Engine Light (CEL) will continue to remain ON.
A stop watch or an analog clock with a second s needle will be useful.

Operations Procedures

1. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
2. Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds.
2a. Fully depress the accelerator pedal (HARD).
2b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.
4. Fully release the accelerator pedal (while the CEL is still blinking)
5. Wait about 10 second.
6. Fully depress the accelerator pedal and keep it for more than 10 seconds.
7. Fully release the accelerator pedal (The CEL light will continue to blink).
8. Turn ignition switch to OFF position and now you can start the car. The CEL light should be gone.

If the CEL light continues to remain ON, repeat the above steps. Timing is EXTREMELY critical to resetting the ECU.

Accelerator Pedal Release Position Learning

Operation Procedure
1. Make sure that the accelerator pedal is fully released.
2. Turn ignition switch ON and wait at least 2 seconds.
3. Turn ignition switch OFF wait at least 10 seconds.
4. Turn ignition switch ON and wait at least 2 seconds.
5. Turn ignition switch OFF wait at least 10 seconds.

Throttle Valve Closed Position Learning

Operation Procedures
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch is ON .
3. Turn ignition switch is OFF wait at least 10 seconds.
Make sure that the throttle valve moves during above 10 seconds by confirming the operating sound.

Idle Air Volume Learning (Throttle Position Learning)
It is better to count the time accurately with a clock.

Operation Procedures
1. Perform Accelerator Pedal Released Position Learning .
2. Perform Throttle Valve Closed Position Learning .
3. Start engine and warm it up to normal operating temperature.
4. Turn ignition switch OFF and wait at least 10 seconds.
5. Conform that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
6. Repeat the following (steps 7a, 7b) procedures quickly five times within 5 seconds.
7a. Fully depress the accelerator pedal (HARD)
7b. Fully release the accelerator pedal.
8. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 20 seconds until the Check Engine Light (CEL) stops blinking and turned ON.
9. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
10. Start engine and let it idle.
11. Wait 20 seconds.
12. Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications.

Hi fixtmr,
Thanks for your patience. The CEL is not on I will follow the instructions for the relearn procedure and let you know of the results ASAP.
I live in Barbados.
I will go through the procedure this morning and see what goes.

I have tried the throttle position learning procedure and the engine runs smoothly, at the idle speed is still at 1200 rpm.
The CEL is not on when the engine is running.
I await further instructions.

Sorry for the delay in getting back to you. Has the idle corrected itself yet? If not, what else have you tried so we can know where to go next.
