Accelerator Stuck
Discussion
I've only ever had this happen once to me. It was on a Renault 12 TS and it was wear on the internal wire of the throttle cable. i.e. Some roughness in the wire made it stick to the inside of the plastic sheath it was in with the effect of holding the throttle open.
Don't know where to look on the Cerbera, I'm sorry. Others on the site will know better than me. I'd get this professionally checked a.s.a.p. myself.
