First of all, it might help to list what you have done, then somebody will probably have a thing or two to add to your list. Give us some details, how many miles, what you changed, didn't change, checked,didn't check.

no power
I checked the timing,spark plugs,spark plug wires,the exhaust system,coil pack,computer,intake gasket,gas pressure,injectors,02 sensors.It seems like the timing is off ,but it`s ok.The truck is a 1997 F150 it has around 232000km on it.

TPS bad?
I don't know but it might explain the symptoms. Are you able to rev the motor to high rpms under no-load?
Did this occur suddenly or just get gradually worse over time?
ANY work done just prior to onset of symptoms?

What lead to having to change the exhaust manifold gaskets?
An exhaust restriction can cause what you are describing. Any chance something is not right with the gaskets, or something is clogging an exhaust manifold?
And you are certain the plug wires are on the right plugs?

So prior to replacing the exhaust manifold gasket it was running fine, just leaking at the exhaust manifold - correct?
Will it rev up freely in neutral?
Were both sides (gaskets) replaced, or just one?
Are you losing any coolant?

Could it be that same problem that came up quite awhile ago. I think it was, Scrimbaby, or something like that. The broken piece around/behind the harmonic balancer. I don't know what it is without looking for that thread. Didn't she have no power at all and changed out around $1000 worth of parts before finding it. I know he mentioned it started after exhaust work, but maybe that's a coinkydink...er coincidence.
I think the thread was called "Bad loss of power".........

Sure, no problem.
Glad you got it fixed mecanic. What exactly was broken? As best as I remember, there is a "key" or something that shears?????
