Any Suggestions? Okay, I guess this is a long shot but here goes. I have a 2000 Camaro . It has 44000 miles on it. THe check egine light came on about a month ago, took it to auto zone and had the diagnostic check done and it said it was running lean. So filled it with Premium V-Power and a cleaner and ran it on the highway, the light still owuldnt go off. Well went to Cincinnati about hour away and it was just getting worse, when i finally ended my trip the car wouldnt even start back up, went back out there later and it started but when i would get going it seemed like it would take forever to get going. Well got back home and replaced the fuel filter, still no change. Well two days ago i was driving on the highway and it wouoldnt go past 50, i could hold the accelerator and the engine was making noise like it wanted to go, but the poor car just wouldnt, it almost sounded as if i had a really lopud muffler but that it was struggling to go. So i stopped at a light and started going and it wouldnt go more than 30. I dont get it? I dont no much about cars but I mean it only has 44000 miles on it and it runs and sounds perfect accept these past few days, it makes a squeeling noise and wont get up and go like it should? Any suggestions?

Do i just take it to a shop then? Or can a friend check that for me?

Not sure of your problem not much of a techy. However here is some advice don't drive it agian or try to get on it until you find out what the problem is. You may have done more damage to it.

Shell V-power is not going to help you be less
lean. But that's not the problem.
You could try getting codes read again. It's odd
to see only a lean code. The lean code can be
true (dead MAF, disconnected / dead injector)
or it can be bogus (like a dead O2 might produce
a continuous false-lean reading). This latter would
be accompanied by other more O2 specific codes.
If you are not the original owner of this car, you
should pull the MAF out and look for signs of some
foolery (missing screen means someone's been into
it; grinder marks or polished appearance means it's
been messed up; not looking like the stock "Oreo"
type means maybe you have an aftermarket one
that just isn't right for your (stock?) tune.
A bad injector would make one bank lean and show
up as a current misfire (if not bad enough to set
a misfire code).
The AutoZone scanner will not show you any of the
real time stuff, even if the counter-monkeys have
a clue. You want to find someone in your local area
with AutoTAP, EFILive or HPTuners and have them
do a proper logging and find the root cause. If you
can't find such a freebie then a stealership could
do the scan with the Tech-II and at least tell you
what's up.

Ok, thanks. I am not the original owner. We bought it with 20000 miles back in Feb. It was in mint condition looked brand new. It just seems as if its not getting enough gas, its wanting to go, but it just wont. ut I'll try and call some local dealers

I don't see your location but, there are "Regional forums"
down at the bottom of the list that might have some
friendly locals willing to help (this sounds like a hands-on
problem to me) and don't have the same vested interest
in selling you something. Check out the one that matches
your locale and see.

Mass airflow sensor. It's in the intake tract between
the air cleaner and the throttle body. If it's dead or
just "way bent" it will mess up mixture and transmission
action (due to air flow being the basis for load value
that drives transmission line pressures). There is a
chance of it being a blown PCM fuse, or a mis-seated
connector. Rarely does the MAF go bad, itself, without
abuse. No K&N / other oiled-type air filter on this car, is
there?

OK, I took it to Pep Boys last night, and they did a flow chart, and tested all the sensors and stuff and said it was the o2 sensors. So $230 LATER i BOUGHT THEM AND ARE HOPING THAT THAT Is what the problem is.

I think $230 is a bit OUTRAGEOUS. Did they sell you the
rears as well as the fronts, or something? That's almost
dealership pricing. Did they give you a list of the engine
trouble codes, or just say "buy this stuff"?
The O2 sensors have nothing to do with anything over
about half throttle, except if they have gone so bad that
they've corrupted the fuel trimming. And, as I said before,
this would have manifested as O2 engine codes long since.
I half (maybe more than half) suspect a sloppy diagnosis
from the "Boys" that just happens to involve selling you
what's on the shelf.
Well, I guess fresh O2s never hurt nothin'.

That's why I call the "Poop Boys". About the only thing I buy from them are their tires.
I was going to suggest O2 sensors. How many miles are on the car? Has it been driven regularly since it's been bought? Does it chug, chug after 50 or just sputter and die?
As stated previously, have someone check fuel pressure and if there is someone local, have them look at it.

It has 44000 miles on it. And it only died on one particular day, ever since it hasnt died but 50 is the highest it will go. THe rpms will go up but the speed doesnt and it sounds like it is making a chuggin noise. I hope its the sensors.

And yes, it is drivin every day to and from work about 2 miles each way, its my husbands car but i drive it pretty regularly to. We bought it in feb with 23000 miles and its a 2000. But my husband drives it like its some big monster so maybe this is a lesson learned?
