i have a 2001 astra dual fuel van 1.6 8v . in recent months a problem has developed, after much searching i can't find a solution any ideas.
The van runs well and then if i put the car in netural or stop the rev counter falls and goes to zero revs. this is kinda dangerous as i have no controll over when this happens. i have replaced the starter motor, plugs and leads but still no better, if anyone has any ideas please could they tell me as it is becoming a pain, also how do you adjust the throttle cable many thanks barry

The stupid ecu computer or one of the plethora of control valves it uses.
Go to a Vauxhall specialist garage and they will plug it in and tell you what the problem is. Watch out though soemtimes they tell you its the whole ecu and charge hundreds when its just a valve.

This sounds very much like the Idle Air control Valve. They seem to develop a sticky plunger after about 50,000 miles. It`s a simple "fix". You could try cleaning it out, but it doesn`t last long before you`ll need to do the job again. Best thing is to simply replace it, it`s an easy job, any decent , honest spanner man can do it in 10 minutes !

The problem with with your idle speed control solenoid. When you take your foot of the accelerator there is no way for the O2 required for combustion to get into the engine as the air butterfly is closed. The idle speed solenoid will open to allow air to maintain the idle of the engine.
The solenoid is normally on the inlet manifold and can become blocked up. Quick and easy thing to fix.

Since the problem is not intermittent it sounds like your idle simply needs to be adjusted. You would look at a manual or at the engine on normally aspirated engines for an idle screw. In modern engines you may need to have the control module adjusted with a programmer.

Im not especially familiar with that engine but its almost certainley to do with the idle stabiliser or ISV.Very common on vauxhalls and audis,try find the location of it and then remove it and clean it out by spraying the inside with carb cleaner or better still leaving it to soak in ISA(isopropyl alcohol) which is amazing stuff,cleans out all the crap and lets the motor inside work again.HTH

get yourself a tin of carburetor cleaner, remove the intake hose from the top and blast all the black sludge away, make sure you open throttle by pulling cable and spray inside, i think you will find this is the answer and also cheaper than changing valves and sensors

Last time I checked, Congress was responsible for the government's purse strings and laws. Perhaps if the House Republicans got their heads out of their rears, something might be done to fix the problem.

it's a simple fix but your mechanic would surly charge you a few hundred to fix it. there is a little screw in your engin( all cars are in a different location so I cant say for sure) that controls how much gas is put in your engine while at rest. your probably not getting enough gas. find that screw, screw with it and it should all be okay.
