Vacuum gauge

Ugh, they need to make a nice and cheap scan-guage/super-mid that even I can afford that works on vehicles before 96'. Would be nice. If you always walk to work, I'd get a bike cause they're faster and more efficient than walking, especially if you want to be less hard on the knees. A comfort bike would be nice on the back too.

You can always install a vacuum gauge. Low tech but still helpful.

They might only cost 20-40 bucks on ebay. They measure the intake manifold pressure and basically give you feedback on how much load the engine is under, which is good to know so you can feather the pedal and set goals like "accel at XXpsi" and things like that.

Just had a thought: if you're interested in tinkering, you could probably do this for free with a little investigating.

Your vehicle already has an electronic vacuum sensor. If you can locate it and tap into it with a digital (or analog) voltmeter, you could use that info.

The goal under cruising/accel (with most auto transmissions) is to keep whatever reading corresponds to the highest vacuum (lowest manifold pressure).

Psshh, oh well. If I do get one of these things or use a volt meter, how do I know exactly what's going on? any pics of what someone else has done?

They are also a two-for-one. People use them to determine engine health :

Here's one that looks like it's from the 1970's fuel crunch, because it's labeled for MPG :

The Mileage Monitor is a precision engineered vacuum gage. The instrument itself has no effect on performance or mileage, but if you use the Mileage Monitor as a driving guide, you can achieve a substantial improvement in your gas mileage.

If you don't want to install the Mileage Monitor in your vehicle, you can just use it as tool to tune up your engine, for the best mileage.

The highest reading indicates the best gas mileage. Normally, driving at a slower speed will get you more miles per gallon, but sometimes increasing your speed a bit will also increase your gas mileage. Just glance at the gage from time to time to see for yourself.
I have the $14.99 Garage-Pro 2" gauge from JCWhitney, but I haven't installed it. My Todo list is laughing at me .

I haven't looked at this in a while, I found that gauge then looked at this, and realized that I missed Lazarus's plain to see link to what I looked for for 10 minutes. Do you need a tubing kit? I posted earlier in this thread about it.
