well as every body know when engine is cold it is a bit rich in petrol than when it warms supposed to go for normal idling ; but mine isint doing that the idle is very low sometime switches off when i switch the beams on the lights, is it a problem in fuel delivery or injectors sensors or something more worse? rep for the replys :)

what makes you think its fuel related?

it could be the alternator / belt as said above.

x2 check the belt.. then the altonator wires and check the earths...
dont fiddle with the idle screw yet incase its only somethin small.. and sometimes its akward to get the screw back idling the way it was..

its where i would start anyway but it doent help that he doesnt have a rev counter.. also check your battery voltage.. if the belt was loose it would sqeak.. could be even timing.. who knows

Check the voltage on the battery for a start, check alternator / belt / wires / earths.

If all else fails, try a Compression Check.

Has the idling suddenly gone like this or when did you notice this change in idle?

What modifications have you got?

power seems to be ok the car was ok then i take to the mechanic becouse was having the balls of the shaft being broken so basicaly he cut the old one and welded a 4age pod on 4efte base to be a bit long due it was a bit short and 4age has a bigger cup so allowas due im not centre point with the hub any way back on topic it only when i got it from mechanic this begins it
