you are attempting to perpetrate a hoax ,
i do not yet know why

but you are going to have a wee bit of trouble foisting your blarney here .
so far you are UNable to respond to my posted facts with any kind of debate
so

post something from your vast storehouse of knowledge to refute what i have posted .
absent that .
my facts stand .
and you will have proven yourself and your hoax to be a fraud
by default .

ready
begin
i eagerly await your reply .

Maybe what happens is that these ideas are so out there, they actually go full circle, ending up on the useful side. It's probably how hybrids, diesels, LRR tires and Scangauges were ALL invented!

Tomorrow we'll probably see ramman361.

what if it was supposed to be RAMON and he just couldn't spell!

Or maybe he likes top RAMEN?

It's up to me how I spell my name. The scientific method and peer review are alive and well at ecomodder.com even if civility is some times in short supply. Every bit of data is useful for attempting to repeat a result. I have had leaks in my fuel evaporation system tubing that caused a "Check Eng" light to come on. I did not track mpg at that time but the vehicle did not seem to run differently. The vehicle is a 2002 Dodge Gran Caravan 3.3L with EFI and AT. Depending on the routing, a missing vacuum line may cause a lean condition. The fuel in the evaporation capture system could be lost to the atmosphere. Best to look at the vacuum line diagram under the hood or in the repair manual. The overall goal is to use the heat value in the fuel to maximum efficiency.
Take time to review basic principles of chemistry, fluid mechanics, and thermodynamics. This will help put testing on a solid basis and minimize urban myths. It least we will have a way to understand how a modification might work.

I.m sorry.......who are you and why are you making that comment on a thread you haven"t posted on...that has run for 6 pages.

I am so confused

[mwebb]

a missing vacuum line may cause a lean condition.

that is not true
a missing vacuum line on a speed density system such as your s will NOT cause lean condition
Mr MAP sensor cares not if there is un metered air . as Mr MAP sensor only looks at
Manifold Absolute Pressure which is UN affected by even large vacuum leaks that may be present in EVAP lines

Mr 02 sensor will maintain stoich even if a purge valve or LDP is stuck open drawing extra HC into the intake .

just to civilly set things straight

very little can cause lean or rich condition when fuel trim has such a wide range of correction available as your system has

Sorry for the confusion. Messing with a person's name is such a seventh grade thing. The Unicorn Corral so often gets into the area of the Conspiracy Theory mindset. It is hard sometimes to be patient even for those of us with customer service experience.
I am not clear on the year and model of the throttle body system under discussion by Ramman360, so I used a general approach. My current vehicle is likely different than older TBI systems which evolved over a period of years. My 1971 Torino 6cyl was undriveable because of a vacuum leak that would not bother a modern car. Since the van is my wife's car I might ask you to refer to Mrs. MAP sensor.
