car wont turn off
 

1987 / 88 NA 300D 6cyl.

It wont shut down by the key and i had to use the stop lever.

It did slow down with key turned off.

I had just replaced my handbrake release handle.

About 6 months ago i had the IP rebuilt by MTQ they have a good reputation and charged me $2600.

After the rebuilt pump was fitted i have noticed first start it idles quick and un even before slowing the idle and smoothing out takes maybe 20 secs.

Dont know if this is relevant. but have posted it as it is now ideling fast like in the morning when the key is in the on position.

Peace and blessings

Sounds like either your shutoff valve is not getting enough vacuum or it's defective itself. Are there any more symptoms of lack of vacuum, like long brakes, climate system not working properly, etc? If not, then it's the shutoff valve itself.

Thanks for your post. seems some how i have three posts going on the same?
It was the headlight adjuster switch that was leaking so i by passed it and connected the two vac hoses together. Thanks for your time
