My sense is that these components last somewhat longer than first anticipated, probably because of the leaner mixtures we're using, and the no-lead gas. It can be expensive. But you probably could change out the oxygen sensor yourself. It's usually accessible, and it ain't brain surgery. The converter is another matter. Good Luck i had a metro with 250000 with original convertor and 02 the convertor is built into a section of pipe you get the whole thing for 150$ and replace it with four bolts and believe it or not the bolts usually are removable without having to use a torch

What does the code p0420 from Chevrolet metro?

This code is generic and is the same on all vehicles. P0420 = Catalyst System Efficiency Below ThresholdCatalyst System Efficiency Below Threshold. This means that the secondary O2 sensor detects that the catalytic converter isn't working as efficiently as it should. This engine code can be triggered by any one of the following: 1.) The catalyst in the catalytic converter is cracked, clogged, or otherwise damaged. 2.) The secondary O2 sensor is malfunctioning. 3.) There is an exhaust leak. 4.) The computer unit is faulty

Where is the oxygen sensor on a 95 Geo Metro?

It will be screwed into the exhaust pipe somewhere between the exhaust manifold and the catalytic converter. Most likely on the front of the engine on the bottom, sticking out fron the pipe with a wire coming out of it. some were after the cat converter. my 94 is before the cat converter, but the 94 is also a split year I think. I dont know which way they were moving them (before or after). Mine sticks straight out of the exaust pipe about 6 inches below where it mounts to the manifold. If it were after the converter it would definatly be under the car on the exaust pipe.
