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.
