Hi guys, first post after buying my new 2001 WRX :) Cars been amazing but i have a slight issue i was wondering someone might be able to help me with? The car has a set of JDM STI dials installed but every now and then the speedo with drop to 0MPH and thus putting the car in a sort of limp mode so you can't go past 5kRPM. My only experience with JDM dials was in my old Celica and i had the same issue but the speedo just dropped to 0 and never worked again, turned out it was the speed converter that was knackered. Could this be the same issue?

 

 

Many thanks in advance,

Ryan

Mine went nuts once and dropped to limp mode but was because of a disconnected earth off the wiring from sender (from gearbox).  Reattached and all was well.  Yours sounds more intermittent though.  Never hurt to have a check around though, bolt may have loosened etc.
