update on my stalling problem

Post by soccerboss »

Tightened up the throttle cable to keep the revs higher but after a while it started wavering up and down then settled at the usual idle speed so i'm starting to think its something to do with the fuel line somewhere.

Do you think i'm on the right track ?

Sounds like air getting in somewhere. Have you changed the fuel filter lately? (I assume this is diesel)

Hi peter

No its a petrol engine .( a synergie if you didnt read earlier post)
Will it make difference whether its petrol or diesel?

The revs just die off , thats why i thought it must not be getting enough fuel through.

sounds a bit like the aux air valve has given up, does it start with the throttle cable set as it should be without using the throttle, ie just turning the key?

Hi soccerboss

how did all this start? did it come on suddenly or worsen over time?, will it rev freely when it does start?, and does it run rough at all?

the manifold ( as i found out when i took it to the garage) was the first think to go. Then it started stalling when i stopped at a juction etc.
Its had a new RPM sensor aswell as manifold, but its still stalling at junctions etc.

What do you mean rev freely and 'run through'?

Ive just seen your other thread, i would be inclined to follow Jims advise and pay attention to the air temp/mass sensor, the MAP sensor and Aux air/idle valve it does sound like a fuel or air metering problem rather than just fuel starvation.
When you say you had the manifold replaced did you mean the exhaust manifold as that would be more likely to fail, ive never seen an inlet manifold cracked so check its gaskets and that it is done up tightly and not loose.
What do you mean rev freely and 'run through'?
When you do get it to run, can you rev the engine or does it just die when you use the throttle or is slow or totaly unresponsive to any throttle input.
Also does it start to miss and splutter (run rough).

Sorry, don't know anything about petrol engines unless they have a carburetter and distributer.

yes it was the exhaust manifold and yes it will rev happily. it will then drive ok for awhile before it stalls.

Yep it is sounding more and more like the aux air valve, with age they get dirty and sticky, take it off and wash it through with some WD40 and a small (very small) brush open and close the valve inside as you do this to get all the muck out then once clean and dry drip a little light oil in, you should find, as Jim has already said that it will work fine for a few weeks/ months after but if cleaning does make a difference then that is the culprit and it is best to get another. They are usualy abou £50 to £90 depending on the type of valve.
Of course the best and most definitive course of action would be to get any fault codes read off the ecu but if this isnt possible for whatever reason the aux air valve is a good place to start given the nature of the problem.

Im not sure where it is exactly on you car but it will be connected to the inlet ducting or manifold somewhere and will look like this ish :lol:
