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
 
Ugh thats gonnna really suck ,don't tell me its connected right below
the exhaustmanifold . *%(&^%(** design
 
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 .
