hi im new this site so just finding my feet i have just bought my self a granada cosworth 81000 miles on the clock never been welded in fact the only rust in the car is on the o/s/r wheel arch. I have also noticed that the mpg reading is not working the only reading i have on this unit is the miles to empty and some l/h reading which i guess is litres per hour, i thought that was my only problem with the car untill yesterday when i hit the motorway and found no 4th gear and no cruise control, i have read a few older posts and and it seems that it is poss that these are conected is this true i would be very grateful for any help with these issues
