I take it your Z is a Japanese one.

 

The beeping noise is a speed warning which tells you are 70mph. Its not on the UK cars. You can disconnect it some how.

Works a treat (did it to mine) and the chime still works for warnings like your lights on

Heres a pic of the TPS, by loosening the two srews and rotating it you can ajust the tickover.

thanks every one for your valuble advice i will give these a try on the weekend

Don't touch the TPS ... it's not for adjusting idle !!

 

Always use the idle adjustment screw on the back of the engine as described in the link that Andy posted.

thanks for that cheers

Although Eric says not to touch the TPS.

You may still want to check it.

I know the guy before me must have adjusted the idle the TPS as it was at .58v when it should be at 0.4 at idle and 4.0 at full throttle.
