hi here iam again seeking help!!! after 2 weeks back on the road this time my dear old rust bucket decides to give me more head aches. This time i have no revs, ticks over very nice ,but when i put my foot on the peddle nothing.When i hold my foot down on the accelerator the revs pick up very slowly i can then crawl very very slowly forwards.then when it gets going it can do speeds of between 70 to 80 mph . has anybody got any ideas please!!!?
