Hi I,m new to this forum but I have a problem with my Tipo. My car is a 1.6sx liberty (1995), I was driving this no problem until it started to rev up and down on its own. Even at stand still it still reved, I had to call out breakdown on it to get me home, he removed the air filter cover and cleaned the throttle body. He told me that the fuel injectors could be dirty as I could turn it off and wait 5 secs turn it back on again and it would be ok for a few miles. This was enough to get me home but now it revs up and down all the time, I have put some redex in the fuel to see if this helps. Does anyone know if its the throttle body thats need replacing and if so what one to change with.Please let me know if anyone has had a similar problem.
