I have just got myself a decat pipe (2nd cat)
Was hoping to fit it this afternoon after work so I got the car up on the ramp but found the lambda sensor stuck. Tried a long bar over the spanner ect then we tried heat, we got it red hot and it started to move but then became stuck solid again. Im worried I might be stripping the thread out so I stopped as I didnt want the car off the road over the weekend.

Please advise me, Am I likely to need a new sensor? if so where to buy as Subaru want around £280

Impreza wrx STi 2006 (56)

 

Try wd40 work it backwards & forewords. If it still wont move heat it again & work it while hot. It will come out but the threads may not be good. If you need one shop around I think most parts factors will supply them but buy a decent one.

 

i had the same prob. got new one from importcarparts.

 

They want £205

found some on ebay from £39. and a bosch at £75

im just not 100% sure they are any good or if im getting the right one

 

Try Alyn from AS Performance - 0191 4103770
Cheaper than eurocarparts and will make sure you get the right part for your make and model I recently got one for my car from him, faultless service

 

Allparts for me. Wouldn't get an eBay one. Sounds like even with Wd40 the threads will strip. Get one just in case, if not required I'm sure they will refund you.
