numeric racing cables problem

[Paseb]

I purchased 986 shifter cables to match with a 997.2 rs shifter base with a 7in shifter riser in my 2004 boxster S.

the gears are always coming out. i put the car in gear, depress slowly and it comes out of gear by itself.

i had to reroute 1 cable Under my intake manifold cause it was too short, and the other one is still on top.

do you know what could be my problem?

thanks for the help
