Question
 paul harper vauxhall vectra 1600 1999
when the car is first started it runs like its mis-fireing, ive recentley changed the spark plugs but this has made no difference, the engine management light was coming on and i thought it would come down to some kind of crank or camshaft sensor, is it still possible for the crank or camshaft sensor to fail even if the engine management light dose'nt come on? as it dos'nt come on now for some reason, also if i change a sensor do i have to go to main dealers to reset the ecu? or will this just fall into place after it has been changed? thanks for replys
