Just came from OPEL service and confirmed me that there is no MAF in my car a s it is 96 model
Problem I face that now in summer with hot weather and clima working the car gets a little heavy driving and sometimes when I press the clutch to change gear the revolutions decrease so fast that the motor stops. Also when starting to run the car stalls quite often. It is not clutch problem
I guess the problem are the 425.000 kilometers already done and the age, 17 year old car

Recently I have done some service, I have cancelled the inmobilizer, repair the clima as there was a electronic problem and we had to make a new instalation, all the Car Ball Joint from the front wheels as I have to pass the MOT now, nearly 1.000 euro bill, more than the car value.
Hope to not to have more problems in couple of years.
