hey people my dad owns a 1992 j reg 626 2.5 v6 gt abs, there is one major problem that we cannot find out wot it is, the car runs fine and idles perfectly but the problem is that if the car pushed over 4000rpm the whole car completely cuts out an shuts itself down without warning, the revs drop to zero an it jus shuts down, if u immediately turn the car it makes a wierd noise rathet than the noise it would make wen it turns over, but after a minute has passed u can turn the key an it starts bak up again but u cannot go over 4000rpm does anybody know wot would be causing this???[/align]
