I had the same problem used to floor it hard and it would bog down and almost stall...turned out out to be the AFM

Doubt very much its going to be a fuel filter tbh

White indicates its running lean, should be a kind of bronze colour. Its got pics in the back of haynes.

my car has started flooding itself at junctions and started randomly hesitating on accelerating at around 4krpm but sure its my afm and not enough air as its smokey at start up. not run this engine on injection before since rebuild as was running carbs so sure my air/fuel is wrong. got another afm to put on but will be taking it to a tuning guy near me who is really good. not checked my plugs yet but i know they will be black

does it do it when driving?

has it been driven anywhere since the fault started or this all done while idling?

i'd be looking at the coolant temp sensor...

mine did this today when i tried another air flow meter. is a 1.2 though, but symptoms were EXACTLY the same. i put it down to the other meter being dodgy and used my original one. works ok now

or its not getting enough air.

sounds like the car is getting choked somehow.

Not long ago

It was rebuilt recently too

No this completely dies!

i have a similar problem with mine, boggs down when you stomp on the go pedal. if you come up with anything matt gis a shout. :D

under the car at the rear.

Where is the fuel filter located?

Righto will try the filter

Im sure he's already done the paperclip test & it was OK

Dont know how u would test it m8.Another thought try replacing the fuel filter as i had the same thing happen on a golf i had but would only do after driving a while.I spent a fortune trying to fix it and turned out to be the fuel filter clogged up, put new one in and it ran perfectly.

paper clip test for any flash codes

What checks can I do to test this?

Could be overfuelling causing it to stall:boggle:

sounds like an air related problem.

try another 1 it maybe faulty coz it has been known 2 happen

My friend is having a few problems with his C20XE'd Corsa

If you start the car up it idles perfectly fine.

If you rev is slowly it'll go all the way round fine

If you put your foot to the floor it just dies.

Any suggestions?

My first thought was that it could be a bad earth, I know a few people have has similar problems.

The AFM has been changed so I very much doubt it would be that.

Please help :wave:
