Hi:
I was just wondering what year model vehicle you have, and, was there an error light, or something, that made you suspect the oxygen sensor was faulty? I want to believe that my '05 Safari van can get better economy than it is getting but I have not been able to find any solution as yet.

Ya, the 'check engine soon' light was on most of the time. It's a 1988 Astro, semi-cargo, 5 spd

dont feel bad I`m getting 9-11mpg.I went to the dealer and was told thats it.I hate dealing with chevy,and this will be the last one I buy.They sell you a warranty and send you home knowing your vehicle is`nt right.I`m going to change the first two sensors befor converter and see if that helps.
I`ve talked with people who are getting 17-21mpg.I had shepard chevy in lake bluff send me homewith a bad Idler arm.I just drove 45miles one wayafter my mechanic showed me the arm was bad.I was hearing clunks under r.f.I took the afternoon off and took it to shepard where i bought the van.They pumped it full of grease so the noise would go away,and sent me home.Here another oil chnge later I`m at bill kay chevy downers grove getting it fixed and it tsill is making noises.Chevy sucks.Shepard Chevy.Con artist.

Hello, I just bought a 2003 gmc safari and i like the van but the gas mileage is really bad.I am looking for any mods to help increase the mileage?
 First tank i got 17.5 mpg (thats imp. as i live in canada,) thats about 14.5 mpg in us terms.
 
  So far i have put in a k&n filter cleaned the mas sensor and infalted the tires to 35 psi i drive easy about 90 kph on cruise so i will see what milage i get out of this tank.I also removed the roof rack.if anybody is running a chip let me know how this has affected your milage.

Getting between 15-21 MPG is normal. It all depends on factory gearing, wind drag, hills, tire size, tune-up condition, etc. etc.
 
My previous ''95 RWD van got around 21 mpgs. My used 2001 AWD Safari is around 15 mpgs. Yes, A pig - even when going down hill and with the wind. When our "run about" FWD (other) vehicle is paid off in 2 years, our 2001 AWD Safari van is gone. To be replaced with a 2WD vehicle - like Envoy XL or simular shape machine. . Gas savings alone will pay for a much better Tow / family touring vehicle. If you can't get better mpgs, time to replace with something better.

I looked at the sticker inside the door and found that i have the gov-lock rearend with 3.42 gears and my tires are 215/70/16 and that i should run them at 38 psi.So i pumped them up and running easy i get 630 km on about 85 liters of gas.(my old 97 dodge caravan would get 850 km on 85 liters.But i had to retire her and i could not afford a new one so my dad sold me his 2003 gmc safari for $5000 on payments.So i am stuck with it for a couple years untill i pay for it,the milage should go up in the summer,it is really cold up here right now.Other then the gas mileage i do like driving the van.Has anybody here went to a larger tire on the stock rim? i was thinking of going to a taller tire in the summer as my van sits high and the wheel wells look empty.

I purchased my Astro after retiring my second Areostar, which gave me 16-18 mpg consistently. Doing the same kind or driving with the Astro, I'm getting 12-13 mpg. Dealer diagnostic found only that the "fixed" timing was 10deg retarded at idle. They didn't mention the knock sensor, but a local mechanic suggested I check it for a short. Can anyone help me locate it? Things I've done: Plugs, Cap, Rotor, Fuel Filter, Air Filter, 5 tanks of injector cleaner. Engine runs smooth, no misses, does knock on moderate acceleration. Exhaust pipe and muffler glow at night after long uphill pull. Engine really dogs sometimes on acceleration. Help

OH YOU ARE SO FLIPPIN' LUCKY!! I WISH I HAD YOUR VAN!
My '94 Astrovan ( I'm saying all this as I fight back tears) get's like 4mpg period, I swear!
Ok, really, it's probably like 12, but I don't know how to fix the problem! Someone help me!! Either the mpg's improve ASAP, or she's goin' up for sale (or "Free to good home" )
