So replacing the MAP seemed to cure the idle issues i was having but plugging the lambda back in has partially bought them back. I think perhaps both the MAP and the Lambda were screwed....

It's overfueling a bit so as i have a spare lambda im gonna change that and hope for the best... problem is getting the fooker off!!

Im thinking this method a it's properly seized....

- Get some rust/bolt penetrant stuff on it overnight (does this stain driveways by the way?)
- Cut the lead at the top of the sensor.
- Get a socket on the sensor.
- Attach the biggest breaker bar i can find.
- Try desperately to get it off.

What do we think, any tips?

Also should i avoid doing it with the car jacked up if i can? Don't wanna rock the thing so much it falls off the axel stands or something Doh

Many thanks, with a little bit of luck the beast will be working smoothly soon LOL Clapping

have you tried undoing it when it's hot?

if it was me i'd try some heat on it, and then i'd be either whipping the cat off and putting it in a vice or just undoing it with a proper ring spanner and a bit of tube on it for more power after wd40'ing it

Will give it a try with some heat rikky, just need to watch out i don't burn myself LOL

I can also take the CAT off although it's a bit more of a ballache so would like to try and avoid Whistle Probably worth the hastle though as it means getting the job done properly Yes

Now just to find some time to do it Doh

Nearly had a heart attack when i opened the envelope to see nothing, took me a few seconds to realise it had been folded over and the sensor was hidden LOL

Just be aware some lambdas if badly corroded will pull the threads out of the cat as you undo themThumbs down
Did it on my daughters polo, gave it some heat and got a socket on it with a breaker bar and it started to undo, thought I had won!Roll eyes
Untill I tried putting the new one inWhistle

Heat and decent vice grips. But before munching it I'd probably go with cutting it off and popping a socket over it.

Couple of Weetabix before wouldn't be a bad idea.

    if you don't know its the lambda I would not go cutting things, just borrow or buy a lambda sensor socket, though I have yet to fail with a standard 22mm halfords spanner.

    To summarize you could say he made a right mess of her tight rusted ring piece.

    But that would be wrong so I wouldn't suggest that. Just saying you could. Don't hurt me. That's wha

    Noted Yes I have sort of owned the car for over 12 years now though and i know for a fact the lambda hasnt been changed for nearly 10 of those, it's highly lkely it's finally given up Doh

    No chance buddy! The car is at my parents and i don't get back there too often. I am away in a few weeks and then moving the week after so i cant see it happening until mid July. I will take the modified cat pipe off and work with off the car, just cant see how i can easily get it off while under there No

    I will take some pics while i do it so that it's documented somewhere Yes :-)

    You might be pleasantly surprised, I'd try first with it on the car, you may find it comes undone without the need to remove the pipe. Obviously if it doesn't then you will need to remove the pipe, but it's worth a go first. Smile

    In true speedy fashion, six years on i have finally just got this f**ker off! Laugh my ass off King

    I had to remove the cat (in two parts with the custom exhaust) but the bolts to the manifold were all corroded and buggered so had to slowly and painfully cat away with them at a dremel to get them off. Once that was off i was lacking a beefy enough vice so decided to drive over the little bit of pipe where my sensor is screwed in to hold it down in place, 20mm socket and a huge breaker bar and bam it came away Ninja

    So to summarise an oxygen sensor that's probably been on for the life of the car and a section of exhaust that's probably never been unbolted from the manifold since it was bolted together in the first place = an absolute nightmare Doh LOL
