evo 3 2000 rpm engine hunt

[pubsquash]

Hey guys, anyone know what could be going on? Engine warmed up, in neutral start to rev slowly, around 2k rpm, constant throttle it suddenly dips about 500rpm then back up, and dips again etc... If i rev higher it doesnt happen. Doesn't happen at idle either.

Tps or Isc would be my guess.

There is a guide at the top of this section which shows how to check them.
