O2 Sensor P0135 97 Honda Civic EX - Low Idle
 

Need help replacing my O2 sensor on my 1997 Honda Civic EX (Standard Transmission).

I had my CHECK engine light go on & to go along with that a low idle (300 RPM) [almost about to stall in Neutral]. So I brought it to NUMBER 7 HONDA in Woodbridge to diagnose.

After $92 plus taxes, they told me...

CODE P0135 02 SENSOR INOP
** RECOMMENDATIONS **
02 SENSOR INOP, EXHAUST MANIFOLD CRACKED


Apparently, there is a small crack in the exhaust manifold that I cannot see but I am not to worried about that at the moment.

I believe this is the front or Primary 02 sensor, correct?

I called...
Canadian Tire Parts $141
General Auto Parts $ 114.90 - NGK Unit
Dial Auto Parts $135 - Bosch

Any suggestions where and what manufacture to buy?

I have attached a few pics.
