I had the same problem with my 92. Both the mechanic I took it to and the muffler said it needs a new catalitic converter. It is not getting warm enough in the idle mode and that is why is failing.
You should also take the car to a qualified emmissions specialist and have him pull trouble codes. There may be other reasons for your problem.AnswerYour engine needs to be up to operating temperature. My 99 Metro had the same problem and was due to stuck open thermostat. If your water temperature gage does not read in the middle and stays near or at the bottom, then your thermostat is stuck open and you need to replace it. The needle should almost always be at the middle of the water gage and you should pass emissions.
It is behind the throttle body on air filter housing. At 2 o'clock of the air filter housing,
the seal on the crank shaft needs replaced
If they are the same sensor... replace the easy one first and if the code returns, take the old one and replace the other one
Does it have an ignition control module? That may be the cause. Or possibly a MAP sensor or a Crank position sensor or Cam position sensor. Check those first.
I have a 1998 Metro with the 1.3l and the Camshaft Position Sensor is located on the bottom of the oil pan.
the fuel filter is in the tank.
The fuel pump is in the gas tank. While you are in there, you should replace the screen that is on the suction side of the pump. Also, the fuel filter is just outside the tank and should be replaced. Mr Geo Metro firstname.lastname@example.org
what about it?
fuel intake filter inside of gastank is collapsed. Remove the fuel intake line from the fuel pump and blow the filter open with a high pressure air hose.
that must be some metro to have a big block
under he motor mount
it is located on the head
IT DOES NOT HAVE ONElocation of Chevy metro fuel filterits located, so im told, on the top of the gas tank. the tank has to be dropped to change it.
It is possible as the signal from the oxygen sensor is sent to the computer
first up i would replace air filter and fuel filter then get engine tune up if nothing has been changed on vehicle, you should not have to change sensors
connected to the air cleaner housing
Are you referring to a 200 model Metro? If so, there is no fuel filter to replace. 1998-2000 Metros have a fuel strainer in the tank. I have a 1999 Metro 3-cylinder and learned this over the summer when contacting the Chevrolet dealer. Are you referring to a 200 model Metro?

LOL, some dont have crank sensors my friend! if you dont have a crank sensor by your oil pan then you have a bad distributor sensor!
O2 sensor CKT No Activity (Bank 1 Sensor 1)
You won't find one. It didn't come with a cabin filter.
on a 3 cyl.metro,the iat sensor is found on the air cleaner housing towards the rear of the assembly
this could be a number of things, air filter bad gas timing plugs wires rotor cap fuel filter or a sensor. I would suggest starting with fresh gas with a good carb cleaner and a tune up.
you gotta take the old one out first
It is in the diistributor.
The fuel filter on my 1993 Metro LSI convertible is on the left hand frame near the fuel tank. Right by the strut.
