Ok about 3 months ago I had severe misfire problems that were trace
back to a bad coil pack , now I have a similiar problem with power
loss in high gear and misfires at or about 4000 Rpms . I have already
changed wires . plugs , TPS amd MAS sensors and there has not been
any check lights so far . From reading other threads I think I need to
change or check the crank position sensor (Note : I had a similiar
problem on my 95 Scoupe and it just needed the position sensor clean
of metal particles )

I doubt it’s a crank sensor problem. They usually don’t cause
performance issues beyond making the car stall or not run at all.

If it’s actually a misfire, then there are many possibilities left to
check, such as the fuel injectors and compression. But if it’s just
power loss without a misfire, especially at high rpm, my money is on
the catalytic converter, possibly damaged by the previous misfire

Totally meaningless response.

I know ..and your point is ? My point is that the location of the
catalytic convert is not conducive to the use of a non oem replacement
part . Especially since this will be the second trip to the dealer
within a 3 month span .
