Engine Light coming on

I have a 2000 Saturn LW2. The "service engine soon" light came on so I
hooked up an OBD II I rented from a local auto parts store. It said "Fuel
too lean banks 1 and 2" and the same message for banks 3 and 4 ( 2 codes ).
So I ran some fuel injector cleaner through. At the time the car ran pretty
good, but I noticed some hesitation and "chugging" at times when climbing a
hill or accellerating at certain speeds. Anyway, the light went right off
after I ran the injector cleaner through, but then came on again within a
few days. So more injector cleaner and better quality gas. Light still on.
Then I changed out the fuel filter. And the car seemed to run better, but
the light stayed on. I disconnected the positive terminal of the battery
for a few minutes and the light reset and was off for about 20-30 miles.
Then the light came back on. The car is "chugging" again. Maybe I got a
tank of bad gas?? Any ideas?? I hate to bring it in and give someone $85 /
hour if the answer is something simple that I could do.

Always make sure you disconnect the ground cable first. Safety issue.

I don't know the answers to your questions, but I do know the above.

In short, if you disconnect the positive cable first and touch ground
while doing it you can have quite the fireworks display and/or
explosion.

Very good detailed explaination of this at

That is all you really needed to say.

If you tried changing the fuel filter, then I'd guess it's some kind of
other restriction in the fuel system, or maybe there's some problem with the
fuel pressure regulator. Could also be something like a vacuum leak, too..

And you didn't need to say that.

Unless you don't care that the guy might cause himself big problems
from a simple procedural error.
