This is normal and will be okay if you drive the car for a couple of miles it will relearn and ide down. Make sure there are no vacuum leaks here is a guide to help.

The car is a 1600cc automatic transmission electronic throttle 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.

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.

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.
