why buy a vacume guage all that will do is tell you manifold pressure won't it, and can you attach it to any of any of the vacume pipe on the throlle body with
a t conneter

and it can be used to show how hard your engine is having to work. the TIM Vacuum gauges work really well (about £25 on ebay).
especially useful on the motorway.

exactly. your vacume will become less the harder you press the gas, so being able to monitor how much vacume you have will tell you as rodd said, how hard its working. when i accelerate and am going for mileage i try not to let the vacume guage read below -8 psi. during engine braking tho it goes up to -24 psi. food for thought.

Thanks guys for the replies, keep 'em coming

some thought on what mikedudley said on engine braking,
i've read in some HONDA forum that the engine is supposed to cut-off fuel supply when engine braking,
so it would turn out that you consume less fuel when you engine brake
than when you put to neutral and idle down to a stop.

can this be correct? and does it also apply to Daewoo's

Isnt this why you've a vacuum pip going to your fuel pressure regulator?

this idea of fuel supply being cut off when decelerating has only been used in some newer german cars (mostly VAG engined cars). not all cars/engines have this ability, and most, especially older engines still inject a miniscule amount of fuel when decelerating to prevent the engine cutting out.

^you can get vacume guages at your local parts store. (most of the time.)

doesnt the motor also use part momentum to keep the engine alive as well???

can't be sure but when you start to decelerate your ecu will still detech the car is still moving by the speed sensor and adjust by only allowing the fuel it needs to keep the engine runing?

thats pretty much it. momentum does play a part in it, but there is still fuel.

on cobaltss.net guys were talkin about how when they downshifted and reset their mpg guages, it would read 99.9 mpg lol.
