reluctant on low revs

[mbcamper]

This might just be a trait of T25 vans, but it's possible I'm finding this more... it's amazing what you get used to over the years.

When you first start up in lower revs it feels like the van is low on power and then suddenly it picks up. It's the same hot or cold. I particularly notice it when I'm trying to reverse the van in my drive where it's a fine balance between stalling and keeping it going.

There is a pipe going from the distributer to the carb (vacuum) and if I pull it off the van idles badly.

General driving is fine, I just find you need to give it quite a lot of revs to get it going... is that normal?

Van is a 1.9DG 1986 standard everything.

Thanks

idle speed cut off solenoid may be stuck

Sorry it's taken me ages to get around to looking at this again.

Can I just unscrew and clean up the solenoid?

I'm wondering if it could be a partially collapsed vacuum pipe between the carb and distributor. The reason I wonder this is if I disconnect the pipe at the carb end, the van instantly runs badly. If I disconnect it at the distributor end, the bad running is slower to take effect.

Thanks

You can unscrew ot and see if it is clogged up
The solenoid opens with 12v applied to it
Removing the vac pipe from the engine will make it run badly.
Because you are weakening the mixture.
