Cleaned throttle body on my z and now car wont start. Wait a whole day tried again and still won't. I was wondering if I manually touched the butterfly valve in the throttle body can tht mess my whole throttle body up. Need help asap

I don’t think you should manually touch the butterfly flap. It could mess up the calibration with the TPS. Maybe do a double check to see if the TPS sensor and MAF sensor are fully plugged in. Also is it not turning at all or starting but not staying on?

I already touched it a couple times cleaning. And no the motor cranks but just doesnt start.

Also the throttle body moves too

When i turn key on it mskes a whine noise but when i turn it off the butterfly valve opens and closes

if u didnt unplug the battery your screwed

I unplugged the negative cable before cleaning

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 to “ON”.
3. Turn ignition switch to “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.

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. Confirm that the accelerator pedal is fully released, then 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.
7. 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.
8. Fully release the accelerator pedal within 3 seconds after the CEL is ON.
9. Start engine and let it idle.
10. Wait 20 seconds.
11. Rev up the engine two or three times and make sure the idle speed and ignition timing are within the specifications.

I cleaned it once and it only messed one of the O2 sensors
