Smoke machine vac leak diagnosis?

[andrewwynn]

Adjust your idle up. I used my foxwell 510. Usually boost of 60-80 is enough to get rid of the red light in drive shakes. Car idled perfectly fine in neutral but shook enough I would put in neutral pretty regularly at red lights.

I returned the idle to normal. Easy peasy.

Since then, a year ago, I've noticed an interior rattle, when sitting at a light, occasionally. It's to be expected on a 23-y.o. vehicle. But, I'm going to raise the idle again, anyway, just to see if the infrequent rattle goes away. It might just work.

I've got a decent smoke machine, but the rubber glove trick (over the intake tube, in my test) didn't work, as my gloves kept tearing (medium size, 4 mil thickness) and leaked all the smoke out at that point. So, last week, I bought an AutoLine Pro Universal Bladder Adapter for $25, from Amazon, and will use that device to test with next time. It should do the trick. I may or may not have a vacuum leak, which so far, I've been hunting since October 2021.

Sweet! Just ordered the Foxwell. Been meaning to do that for years. Keeping a laptop updated is just unsustainable.

I'll try with the smoke machine trick as well. Really curious to see if I can find anything.
