Something odd is happening on my 2000 C5. I am doing all of my tuning and driving in Speed Density mode, and it seems every few drive cycles, I get reduced power, and have to go in and clear all the dtc's. Here is the list of DTC's I get.
Diagnostic Trouble CodesP1514MAP/MAF - Throttle Position Correlation P0103Mass Air Flow (MAF) Sensor Circuit HighP0106Manifold Absolute Pressure (MAP) Sensor PerformanceP1514MAP/MAF - Throttle Position Correlation P0103Mass Air Flow (MAF) Sensor Circuit HighP0106Manifold Absolute Pressure (MAP) Sensor PerformanceP1514MAP/MAF - Throttle Position Correlation C1278
Mods are.... 224/228 cam/ Crane 1.8 rockers, 42lb injectors, AFR 205 heads, and Headers/exhuast. Running OS5
Any input would be greatly appreciated, I don't see why I should get reduced power. Car runs and drives great, except for a rolling idle issue I am still trying to sort out.
Thanks
