I got my nGauage, finally hooked it up today to check the DTC's before loading the tune. I thought I had 2 DTC's, but there are 5. I'll list them below, if someone doesn't mind, please let me know what I need to do to have these fixed and if they are a big deal or not. P0030 HO2S Heater Control Circuit P0053 HO2S Heater Resistance P0135 O2 Sensor Heater Circuit P050B Cold Start Ignition Timing Performance P2138 Throttle/Pedal Position Sensor/Switch "D"/"E" Voltage Correlation These are straight off the nGauge. Thanks in advance.
