Hi, i have Subaru legacy 91, noticed that my O2 sensor was failing fuel to bad odor to gas in the exhaust... so i replaced it for a new one(universal i had to crimp the wires myself), the idle was nice, no more bad smell of gas, i went for a test just around the block with no issues. But today i went to work and when tried to accelerate (between 2k-3k rpm) the engine hesitate, I had to release the pedal and start in low rpm's. I didn't have that problem before replacing the O2 sensor...

Wat happened? I though it will be better. May be the new O2 sensor is bad? any ideas?

Thanks for you help.

if it didnt happen before you replaced, it's more than likely the part you replaced. might help to replace with OEM
