Egg smell + black smoke from exhaust

[J273]

I've just drove home from work with no probs...I've just gone to start the car again and it's struggling to start ....will start but is struggling to run trying to cut out+ black smoke from exhaust and smell of eggs.


The lights been on and off on the dash for a while now.

Are these the symptoms of a dead cat converter?

Thanks

As said really sounds like the cat.

 

[J273]

Yeah thought maybe so....should there be black smoke then with a dead cat?

Thanks

 

[J273]

Managed to get a new cat now...hopefully that's the problem.

I've just been put to try the car again ..starts fine from cold and then once it's Been running for say 2 mins it starts to struggle and trys to cut out...also stinks of gas in the car.

dead cat i recon and possibly the lambda sensor too... de-cat is easiest bet and will sound like its meant to

That's the cat Ive bought...I'm guessing its coming with a lambda.

Which ones this from the pic?..Is this the one which puts the light on the dash?

Thanks

Yes that exactly the problem ive got.


Also runs the same from the video posted.

Edit:Ive got a OBD2 U380 diag scanner....would this tell me the problem?

No dont think it helped Daz. Just borrow someone elses sensor, its the black thing on the RS inlet, L/H side iirc. Only push in.

Yeah Ive got a replacement on the way so hopefully it'll be one or the other.

 

[J273]

One last thing....Ive got a replacement lambda sensor here.

Ones on the cat ,wheres the other located and is it easy to do ?

Thanks

Other one should be around the manifold area. Best way to check for a dud cat is to unbolt the cat at the front of it, then try and start it. If it starts and revs fine....

the CAT wouldn't cause this though. The lambda does nothing post CAT, so even if the cat was broken the flow wouldn't be much different, unless it's in pieces inside.

Sounds like the map sensor from daz's post tbh. Hope the new one sorts it.

 

[sussex_gti]

Sorry, meant to put if the cat was broken inside causing a blockage. My bad!

 

[J273]

Yeah I'm thinking it's the map sensor from daz's post.

I'm confused though with the lambdas....which one is the one that actually does somthing ?....is it the one on the cat or before the cat?

Thanks

 

[J273]

Any tips on getting the map sensor out?

Don't fancy it snapping off inside?

Thanks

 

[sussex_gti]

Good soak of lube and plenty of paitience.

 

[J273]

Will washing up liquid do?

Also best just to pull it straight out or one side first?

Thanks

 

[J273]

Hmm...can't seem get the sensor out.

What's the best lube to use ?...wd40?

Thanks

 

[sussex_gti]

Yep, should do it. Just give it a slight twist and be paitient. Doesnt go too far into the inlet iirc, so shouldnt give any problems.

 

[J273]

Fixed.

Was the map sensor...replaced it today works fine now


Thanks all.

 

[J273]

Since replacing the map sensor...the car pulls like a train.

Is this just me or does a map sensor make that much of a difference?
