eddies92lx

hey I picked up a 92 lx 5.0 about a month ago and today I was putzing around under my hood and i noticed that my egr was unplugged, does that matter? the car has a smog delete I dont know if that makes a difference.

a lot of people d/c them. people argue whether or not it help or hurts more, supposedly you get better gas mileage with them connected, but mine is d/c, and i get 21 mpg

lol....hmmmmm maybe we're on to something here, emissions actually hurting gas mileage....just not possible

egr is there to queench cylinder temps to reduce NOX.... AND THE SMOG/ THERMACTOR AIR SYSTEM IS to aid in heating cats up asap to reduce cold start emissions

yeah, but if you're not overly concerned with oxides of nitrogen, or the production of them, then its not that big of a deal. they are only made in high quantities when your combustion temps get really high, such as a lean condition. i think most of us will probably have more of a rich running condition......lol, ill give you an e-cookie if you know what TAB and TAD solenoids are off the top of your head

Come on...don't make it so easy on me!! TAB = Thermactor air bypass .......TAD = Thermactor air divertor
