I have a Cavalier with an Ecotec !6v engine in - I bought it when I sold my beloved Astra SRi and the bloody thing has cost me £1000 plus already - The engine cuts out at random and sometimes I have a hellish time getting the thing to start properly - It turns over and fires but then dies again!
I have had the following things replaced.
Had the air pipes cleaned out
Nothing solves the problem.
I have one of those ecotek power boost valve things fitted but I have run it with this open and closed with no change!
Can anyone help? I know 16V Vauxhalls suffer from sticky valves but this is a nightmare!
