Double check that everything is correct. Is the lid fully secured and the clips on the rear in place? If so you may need to check that the filter is seated correctly. It could be something as simple as that if, you did not have the problem before you changed the filter.

Did you plug in the air mass flow sensor after reassembly?

Good point, I had forgot about that as it was the easiest bit of the job.

Hi woodso
Thanks for your reply. No no problems before at all. Before I plugged the two way connector into the airflow pipe. Noticed oil so wiped both ends sprayed with iso electric cleaner. Plugged it in.. Drove fine at first drove a mile. Stopped on second switch on came on after judder.. Just been to a garage. He plugged it in said it gives a ignition electric fault.???

Is that the two way plug that plugs into the airflow pipe?

Is this it. Its the only thing I disconnected. It was really dirty got isopropyl spray and cotton buds cleaned it. But only after the light came on the dash.

 

[Woodso]

That looks a bit dodgy to me. Is the flex really covered in tape? It doesn't even look that the plug is fully home in the socket.

 

[Cathy]

Yes that's how it was before. Covered in tape. Can't psh it in any further. Do you think it could be the connector. Is that the airflow sensor?? Thank you so much for your help.

Are we sure that isn't the MAP sensor?

Ah right thanks. can it be taken off to clean. Took the pipe above it off, and It looks like it's a part of the air intake pipe.

I don't think the 156 has a MAF, so it has to be something else.
After spending far too long looking I think it's this : What is this sensor?

Ahh that's interesting. Thanks for spending time. Obviously it's not the reason my car struggles to start. Can stop looking myself. Been on the car for days. Booked in for Monday. Hopefully find out the mystery. Wish I'd left the air filter alone.

That big pipe supplies air the smaller one maybe what's termed as a "wet sensor" monitoring the oil vapors into the Turbo housing
