o2 sensor

[raymong]

hi will a bung front o2 sensor on 7 wrx cause the car to be pulling timming and running in limp mode so it doesn't damage itself since it can't read proper AFRs?

the car idles real rough and pulling less vacuum, and it overall runs like garbage

i did bang the o2 into the chasis quite afew times as i had to pull and put the engine in afew times to sort some issues with aligning the clutch plate ..

02 sensors dont like being dropped or dinged

Yeah o2 sensors are quite fragile as such . It probably wouldn't pull the timing . . . Might be wrong though . . . But mine idled shit with no o2

yeah i had a bung o2 sensor, was running rich as with a real unsteady jumpy idle. replaced it and its like a new car again, and using about half the amount of gas!

the v7 onwards subbys have heaps of fandangle codes and ways of running the ecu..

done some research on us forums and most of them have v7 onwards and say that the o2 made heaps of difference

so will defitnately change it and see if it makes a difference

its not throwing cel's but im sure there will be heaps of codes if i got it scanned.

it defitnatly got some punishment when the engine was going in..

U sure it's not a vac leak somewhere

Usually with front 02 sensors if it's not reading right them the e j wil throw a system too lean code

That's if the sensor is still sending it data otherwise If sensor is bung then it will have o2 sensor code

Either case will have check engine light comming on in the least

Get someone in ur area to do a diagnostic and reset the ecu

Should be cheap enough
