Anyone using this cordless battery smoke machine?

I was thinking about buying this cordless smoke machine made by Autoline. I am trying to find false air coming in on 84 m10b18 L-Jetronic that is causing a high idle. Anyone else using this machine?  Here is the link:

Why do you want battery smoke?

 

What’s false about the air - is it not telling the truth?

Dunno ’bout smoke things but i’ve used start pilot for similar issues with success.

False air is unmetered air if you have L-Jetronic fuel injection. It raises the idle if you have leaks.

Yeeps- not at that price!

 

Smoke's the trendy new (ok, not so new, just becoming popular)

to find air leaks in intake tracts.  It's a useful tool, but for older 

non- DI cars, it doesn't simulate the vacuum the intake experiences.

 

I have a $50 smoke pot off ePay and an air regulator, and it does well enough...

 A smoke machine is a very useful tool for a shop, mine has always had a couple of different ones----a higher-pressure one for finding boost leaks in turbocharged engines, and a low-pressure one for finding leaks in the evaporative emission control system for modern cars.

 

Since the average hobbyist probably won't use a smoke machine very often, you and a friend or two could split the purchase and pass it around as needed.

 

As for your 318i L-Jet engine, unmetered air usually causes a rough, low idle versus a high idle, but smoke testing is always a good idea. Remember to smoke-test the crankcase of the 318i engine----a cracked breather hose or even a missing oil dipstick seal can cause idle issues.
