Hi, I am having a problem with my 1991 G60Corrado when i come up the hill on a local bypass my corrado decides to hold itself at 83mph i have oversized wheels on it and it is probably doing about 90mph really. It doesn't happen unless i am going up a hill and it doesn't do it everytime but most the time. When this happens it will hold there for a while and then suddenly just kick out of it and get going again. Has anyone got any ideas please help. Thanks
