EA won't rev, no power, HELP!

[AshMan]

Gday,

I have been a pround owner of several EA falcons, this one being a 1990 EA Falcon S.

Has the 4 Speed auto and MPFI.

The car starts easy, and idles perfectly, but has a distinct lack of power and will not rev out over 4000 rpm. This is in any gear, even in park or neutral.

Becuase of this, of course, sometimes the auto won't change up because the engine won't rev high enough to initiate the change.

I have replaced the plugs, MAP sensor, TP sensor, EGO sensor, fuel pump and fuel filter.

None seemed to make any difference.

I know that the 6's aren't the best on fuel, but I think maybe I should be getting more than 350km to a tank?

I had the car dynoed because I was interested in if it was as really as gutless as I thought.

My suspicions were confirmed, 82horse power!

I am running out of ideas.

Another thing that is probably worth mentioning is that, you know the little connector next to the battery that is to be grounded to set the base timing? well that does nothing. And it's not just the idle control motor, becase it doesn't even lock the timing in!

I'm thinking maybe a computer or electrical problem?

Any help would be greatly appreciated!

Ash.
