boost gauge needle sticking

[daveyfx]

As the topic states, the needle of my boost gauge is sticking, as in it is slow to respond.

When I installed the gauge initially, it was just fine. I would fire up the car and a second later, the gauge would read vacuum.

Several days after installing the gauge, I noticed it was very slow to garner an initial reading. Now I have to wait about 2-3 minutes for the gauge to go from 0 to a vacuum readout.

Replacing it is out of the question since it is a discontinued Defi D-gauge gauge.

Help!

Hmmmm thats weird, id ###### just go buy a new one. I no you probably dont want to hear this but you can get boost gauges for very cheap on ebay or in the classified section.

What I'm more curious to know is if the sticking issue will gradually worsen and cause the gauge to become inoperable. If it won't then I'll keep the gauge and deal with it.

It doesn't seem to stick when the car has been sitting for several hours. Only if I let it rest for a couple of hours (or less) will it stick for a minute or two.

Well, if that is going on, I'd swap it ASAP, if it's sticking, you may not be getting an actual boost reading, which could make life very bad for you. Just go with an autometer gauge. IMO, you won't find a better quality gauge. Inexpensive as well.

What I mean is it will sit at dead zero for up to a couple of minutes and then read vacuum. I know that it is reading correctly after it budges from zero finally

So I noticed a new and interesting issue with the gauge today:

Occasionally, after running the vehicle I can shut her down, watch the needle float back to zero and then restart the car. Now when I do this and shut her back down while the needle is at zero, the needle will quickly fly down to vacuum and then float back up to zero just like it should when the car is shut down.

Could I have botched something in the install possibly?
