If you have two hoses, put the block in one, then swap for the smog
test. Experienced smog operators could spot the disabled or reduced EGR
just by listening to your engine as you drove in.

Reduces nitrous oxide. Hopefully somebody will figure a better way, as
there is pretty good fuel savings running with higher compression and
combustion but that also increases NOx...and with the new congress
already blowing about "environment" this doesn't look like good times
ahead for auto enthusiasts.

Think most systems do check for the amount of exhaust being
recirculated, so would expect a code on most mods. With modern FI it
tends not to be as bad as the older stuff when EGR first started.

It did on my old 78 Dodge with the 'lean burn' system; it was set up so
that the valve was wide open at any throttle setting except idle, and
the mains were oversized a bit to compensate. After rejetting, I ended
up with better throttle response and another 1.5 mpg, which was a big
deal because it only got 10 mpg to begin with.

Another old '74 wagon I drove ran like a champ with the vacuum tube
removed. No one I knew ever left theirs hooked up. I know the vacuum
controls on EGRs now are more refined, but the idea of shoving exhaust
gasses back into an engine to lower combustinon temps still seems silly
to me. Even water injection made more sense to me.

Figures. I'll probably get a code, but I'd like to see how much better
it runs just for laughs. There's always a way to get around something
if you really want to. Truckers figured out a long time ago that
getting around computer governors was an easy task, IF you didn't mind
the speedometer being disabled. Nowadays we get a code set on that too
if we mess with input sensors.

Re: "SW" Here's a Goodie! Re: cold start sluggishness
 

There you go again, the jealous, REALLY JEALOUS, over the fact that
I once own a '37 Lasalle, what a jealous little draft dodging senile
coward from Gulf Breeze, Florida, who's only way to get attention is to
make a fool of it's self. With this goat obsession/fetish you have. Like
when the other kids laughed at it's attempt to use foul language in
elementary school play grounds, but just gibberish. Too senile to
remember what he last wrote. You remind me of a little rat dog, like a
Mexican Chiwawa with it's senseless barking, me too, me too. And as
usually afraid to use your name, address, or even sign your statement as
any man would.
Again you don't even have the fortitude to sign your lies, what
coward!
You're not worth any more time when a cut and paste this same
paragraph it fits so well!
But now worth the time to forward this low life to: abuse@mchsi.com
