Hi All,

I own a Fiat Punto 2002 16v ELX 1.2, just recently picked it up.

I had the CEL (Check Engine Light) few weeks ago, on the first day it was on went to the garage, the mechanic tested the car and gave me this Error code:
P0135 - he says it's Oxygen Sensor.
Also, he said that sometimes it just jumps and he deleted the malfunction and told me to keep driving it. if it comes back give him a call and we will replace the lambda sensor.

The problem came back and I kept driving the car for another week and half with CEL on, gave him a call today and he said it needs to be replaced.
MERPHI - worked for my favor i woke up this morning and the problem is GONE ?

What does this means ? should i replace it anyhow, or it might be a fault reading ?

Thanks in advance...
Idan
