Gtb Won't start / Running rough

[Guest]

Hey guys and gals I have a 96 bg5 legacy wagon. Yesterday I was driving home and under acceleration it started coughing, then i couldnt hold a constant speed, eventually i pulled over and it died. It would start and idle REAL rough for about 5 seconds then die. I couldnt accelerate at all or it would die.

It is acting like the afm is unplugged. I was tinkering around checkin everything was plugged in and i came across a thing on the intake manifold. It screws into the manifold at the top of the engine and it has a air hose coming off it going away somewhere. It looks kinda like a sensor of some sort.

The plastic tube snapped off when i touched it, Does anyone know what this thing is? and if it would cause the car to run so roughly??

Pleaaaaase help me!

Check engine light? Will tell you if it's the AFM or not.

the screw in thing. front and centre on top of the manifold right? That thing i think is simply a filter for a vac line. the vac line will go off to the BBoD, or somewhere and play some obscure yet crucial part for the TT system... Um, to replace it just find any BG/BD GT at a pick-a-part. Or head down to a dealer and ask for a new one.

cheers i believe there is a smell of petrol out the exhaust at times too perhaps its not burning right? that bit brand new would probably be some ludicrous price ill try pickapart first. And ill check the fuel pump ova the wkend

cheers for the feedback

Ah the GTB woes... Man what hapenned i dont sign in for 6 months and i loose all my post history, Grrr !

Sounds like AFM, mine doing the same, intermittently runs rough and wont accelerate, coughs and splutters... then runs perfectly. No CEL codes tho... You getting black smoke out the back when its coughing? I think thats a sign the fuel air mix is up the duff ?????

How long since the spark plugs were changed?
