O2 sensor replacement
It's been running a bit rough lately, and I assumed I needed a tune-up. It's getting dramatic-not wanting to start, shaking, moaning...then actually shutting off after it's started. The auto store with small diagnostic tool said the code was for the 02 sensor. One store said it was the sensor going bad- the air/fuel ratio off hence the chaos. Another (I checked with two) said the code did not necessarily mean sensor was bad-it may be responding appropriately to another issue, with which I agree...I am going to clean the sensor that is attached to air filter hose...as per recommendation...maybe get that tune-up... any other suggestions?
