Having just fitted new alternator and everything working as it should,2 days later right hand engine management comes on when revved and goes into limp mode will not achieve above 20 mph I am almost at the giving up stage no idea what is causing problem .Am still a bit knackered from alternator on Sunday everything seems to happen now as I need the old beast to ferry my wife to an from Newton le willows to visit her terminally ill sister. Any body got any ideas of what is happening I would be eternally grateful I afraid to drive any where due to very low speed achievable.
