OK just did the sea foam deep creep cleaning on my 95 Disco... Ran fine after... but the Check engine light came on, and the OBD under the passanger seat was flashing "48" when I turned it off and restarted it it flashed a "34". I'm extremely new to the disco and was wondering if anyone out there could tell me what that means. On the good side, I now know that the OBD reader actually works... Always have to find a positive.... | ||

If #29 is detected again, substitute ECU & re-test. #44 Lamda Sensor A, Left Hand. #45 Lamda Sensor B, Right Hand. If both codes displayed, check voltage to heater coils. #25 Ignition Misfire... Followed by Right or Left codes... #40 Indicates misfire on Left Bank #50 Indicates misfire on Right Bank If #40/#50 displayed, check: 1) Dist Cap. 2) Rotor Arm. 3) Coil. 4) Elec Connections. 5) Pick-up (airgap @ dist). 6) Amplifer. 7) Injectors (if code #34 or #36 are displayed). If ONLY #40 or #50 are displayed, check... per bank: 1) Spark Plug on that bank. 2) Plug Wires on that bank. 3) Dist Cap. 4) Injectors for that bank. #12 Airflow Meter. #21 Fuel Tune Select...

Right, Causing engine to run rich or lean. #14 Coolant Thermistor. #17 Throttle Potentiometer. #18 Throttle Potentiometer... Input high -- Airflow Meter low. #19 Throttle Potentiometer... input low -- Airflow Meter high. #88 Purge Valve Leak. #28 Air Leak... Check for Air leaks in the following areas: 1) Hose, air flow meter to plenum. 2) Breather system hoses to plenum. 3) Vacuum reservoir hose. 4) Dist Vacuum hose. 5) Hose, purge valve to plenum. 6) Injector seals. 7) Gaskets, inlet manifold, check all. 8) By-pass air valve hose. #23 Fuel Supply... Check system pressure. #48 Stepper Motor... Check Base Idle speed and/or speed sensor. #68 Road Speed Sensor... Check sensor. #69 Gearswitch. #59 Group Faults 23/28...
