hi,i have recently bought a 1996 1.8 petrol vectra,it has failed its mot on the exhaust seal at the front leaking gases,also told there in no middle box and cars emissions are too high,my engine management light is staying on and the engine revs are going up and down on idle. are these all normal symptoms for the exhaust fault or could there be another fault ?

Easiest thing to do is have the fault code read out. Takes away all the guesswork.
Fortunately as your car has a petrol engine and was made before 1999/2000 you can do this yourself by means of a paperclip and the instructions from the following website.

As regard the idling, I suspect the idle speed control valve could do with a clean. See:-

thanks but do you think its could be a good possibility that it is the exhaust which is causing the engine management light ?

Could be. Fix the leak and see what happens.

The erratic idle could be linked to the exhaust, or a sticky idle air control valve, a very common problem on many Vxs of this era. Let's see what the codes are and go from there.

Paperclip trick, as previously mentioned.
