My Astra CDTi has cut down to tickover and will not rev on throttle fault spanner comes on . It has happened before but cleared by turning ignition off and restarting. Tried this but no joy


run fault codes and check for accelerator position sensor and other related faults. Faults have to be physically fixed so turning the key off and on will do nothing to fix a problem

I wish to adjust the idle tickover speed a wee bit on a 2007 Ford Transit 2.2 Duratorq engine. It is currenlty ticking over at approx 800 rpm and is hunting at this rev. If I could raise it a wee as I do...


First ensure that the throttle interior is really clean, a surface layer of grime can upset the ECU's ability to meter and govern the air entering the engine. If the throttle body interior is found to be really oily and dirty check on the idle air control valve and make sure that it too is cleaned up. Next put the ignition switch in position 2 (on, but no start) and depress the accelerator fully and release. If there is an issue with the throttle position sensor this procedure can help the ECU relocate the throttle plate position. Start the engine and if it is still hunting locate the air mass meter (AMM) on the air ducting immediately next to the air filter and disconnect the electrical connection. Does this remove the hunting aspect?... the rev speed might change but for the moment concentrate on the evenness of the tick-over. If the idle is even when the AMM is disconnected but hunts when connected then look at replacing your AMM. Try spraying the AMM with no residue electrical cleaning spray to see if this improves matters.

Problems accelerating


the engine tickover is too slow when the engine is cold its running on cold start, ie:choke,, after it warms up the engine slows down this is what is causing it to stall in gear,, get some one to hold the brakes hard on and with the engine running in gear ajust the tick over till its reving at 750 - 850 rpm the revs will go up a bit when its out of gear,, before you pick a gear to go into push the foot brake down to stop the car lurching,,,

Hi ,my ford granada mk2 1984 ghia x is poorley, cant find the problem nor can other garages, the car runs ok on tickover select a gear and it hunts then stalls, changed the carb,gearbox ,plugs dizzy, leads...


The garages you have used sound like they should be avoided: Gearboxes, dizzys and leads never cause hunting and never will. Hunting is always caused by too lean a mixture but is rarely due to a carb adjustment error. When you engage gear, the engine load increases and increases the depression in the intake manifolds.

You have an air leak somewhere in the intake side of things which, it's more complicated on your model as it's a V6 so there are more places to look. Prime suspects are the intake manifold gaskets and possible hairline cracks in the manifolds themselves.

Any decent garage should be able to diagnose and fix this without any problem at all, but on the V6 the labour costs can be a bit high if much needs to be dismantled. The good news is that if you're an enthusiastic owner then you don't need to go anywhere near a garage...

Join the Granada Owner's Club (see link: unfortunately I've just found that their site is currently incompatible with FireFox, but works fine with Internet Explorer); they're a very friendly and knowledgeable bunch and will always offer advice and practical help to an owner in trouble. The 2.8 Ghia X is always a model which is of especial interest to them. Annual membership fees cost less than half a tank of petrol, so it's an absolute bargain.

You should soon have your problem fixed and be able to enjoy your car: I used to love mine back in the day and it was a rarer variant with the optional sports handling pack. It was fun to have a big car which would run rings around the hot hatches of the time and leave them behind in a cloud of tyre smoke!

I hope that you've found my answer to be of some assistance and ask in return only that you return the favour by rating my answer.

Revs ''hunt'' on tickover, sometimes revs drop so low car cuts out


Thanks to some advice I have fixed the problem with my Granada. The pipe work from the exhaust manifold to the inlet manifold has a short piece of plastic pipe which needed replacing. This seems to have done the trick.

I would like to thank you for running this site. Without it I would still be re-starting my car each time I stop at a red light!
