Running at speeds
Hi My astra has just been serviced in april but on running it at low speeds it does a lot of chugging and runs crap am not getting the full mpg that i should be getting a matter of fact am now only getting about 250mls to a full tank, where i was getting more than 300mls. Wot can the problem be
my astra does the same, the prob is normally EGR valve
If you are getting the engine warning light showing then it's probably to do with the EGR valve. Before doing anything with the EGR change the spark plugs and run some redex through see if that'll clear up the injectors/fuel lines.
better to get a blanking plate fitted to where the EGR valve is,then you can disconnect the EGR and throw it away,as all it does is let exaust gases into the inlet manifold..EEC rules (that don't apply in the UK) have forced manufacturers to fit these to all vehicles,UK MOT stations will not fail cars that have no EGR valves as the emisions that the cars produce are under uk limits.
