On an 89 V6 2.9 liter engine. Trying to find it to wrap foil around it, a little better gas mileage by fooling the computer ?

:D
 
its on the passenger side just before the cat.
 
What? What kind of "trick" is this going to do?
 
Perhaps you could explain why you think wrapping foil around the O2 sensor will help gas mileage?

Foil around the tip inside the pipe? Wouldn't that be the same as clogging an o2 sensor which would cause it to run pig rich? :icon_confused:

Not finding the oxygen sensor is the best thing that could happen.
 
Well, the pipe is down a long time, no more Captain Black : - ) What this is reported to do is fool the computer into thinking its running richer than it is and subsequently lean the mix SLIGHTLY for a bit better gas mileage. Personally, I'd prefer to burn the gas in the engine and not the cat. : - )
Does it work ? Dont know, didnt try it yet..
 
You must be one of those folks that made the company that manufactures the tornado wallet lighteners some profit.
 
What gas milage are you getting? I really dont think you can bitch unless you're getting what Im averaging at 15mpg... With your 2wd street rig your milage can't be all that bad...
If it ain't broke don't fix it...

make sure you can get the cat off first or your gonna be cussin when your trying to figure out how to unstop a foil fouled cat.fwiw don't do it.
 
umm...its going to run like abosolute crap if you do that..just leave it alone.
 
hmm, who knew that a man with some foil could rig somthing up to improve milage....you would that that, after the millions of dollers spent designing things,all they needed was a few bucks for a rool of foil
 
Yeah, it would set some tongues wagging if it would work. I'll know in a couple of days. I know most would simply lie back and relax but can you imagine where we would be if everyone just sat back and let " someone else " did it ? Fred Flintstone and Barney Rubble ring any bells ?

: - )
 
Ya mayswell just take it out and cap the hole. Cant be any better than that.

Dont coem cryng to me when you engine dies becuase its built up with sludge from running to lean all the time.
