I am new to this forum . I have a 1999 manual honda civic. It is giving fault code 105 ( Mechanic told me so )
So accoding to the mechanic the upstream o2 sensor is the culprit .Isthat the right diaganosis.
How difficult is to remove this one . What brand should I buy.
Myother car is 1990 Volvo 240 DL Manual which is quite simple mechanically and electronically and easy to work on moreover great info is available at brickboard.com etc . I believe in collective knowledge of all the owners and enthsiasts.
