Was driving along a twisty B road today having some fun, when the car started limiting itself to 4.5 thousand revs and the check engine light came on. The car is running fine appart from limiting itself, was running a little low on fuel at the time, so i've filled it up now. Was hoping after restarting the engine this would clear the fault but it hasn't. Do i need to reset the ECU? (its a standard MY93 WRX ECU) and if so how do I do this, disconnect the battery for a certain length of time? What could this fault be? Low fuel pressure? There are no leaks of any kind.
Also speedo stopped working yesterday, not my week Stripped clocks out and the speedo cable isn't spinning. The cable isn't snapped either, as if u try to turn it there is resistance, obviously something wrong the gear box end. What could this be? Any ideas on either problem?, ur advice would be greatly appreciated

Its your speedo cable gone mate Probably at the gearbox if its fine the other end.When the ecu cant detect a signal from the speedo it sticks you in limp home mode. I think it was to stop those crazy jap barstewards disconnecting the speedo to get around the 112mph limit in japan

Ps I have a spare half coming from the speedo if you need it.
