Cuts out after starting

[Custard]

Hello I've recently picked up my new to me z :-) its an 03 80k 1 owner from new with full nissan service history.

 

Now the problem only occurs when starting the car and not everytime, it starts and then the revs just smoothly drop till it cuts out unless you lip the throttle then its fine. The revs do seem quite low though when driving, at idle they still at about 550.

 

Thanks for any help.

Leaving your air con permanently switched on should help with this issue

Oh right ok

any idea as to why its doing it?

 

Thanks

Sounds like the car wants a throttle reset/idle set up to allow the idle speed to be correct.

 

ECU Resetting Procedures

 

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.

 

 

or visit a friendly garage with Nissan Consult 2/3 to reset both the throttle and idle speed very quickly.

 

 

hope this helps

Brilliant thanks for that, ill have a go later

Could some of this info be transferred to the How To's?
