Opel Corsa 1.4 utility has a miss what could be the problem?
I have a corsa 1.4 utility , the spark plugs , leads , coil , fuel filter have been replaced with
new parts the injectors have been checked , the mechanics are puzzled here. One
mechanic said 3 of the exhaust out lets are the same temperature the other 1 is cooler ,
the opel carage says its soming to do with the air intake can any body share some insite
to this matter.
They should all be about the same. That tells me that cylinder is not firing properly. Fuel, fire and air. Make sure that injector is pulsing fuel out properly. Make sure that spark plug is firing. Might also have a valve sticking open on that one due to carbon build up. Have you tried some injector cleaner? A can of sea foam to a tank of good gas will help clean the carbon build up if there is any.
