2010 Range Rover HSE Lux
Hello, I recently purchased a 2010 L322 with the NA 5.0. The car had an engine light and "restricted performance" displayed in the instrument cluster, however I bought the car anyway because the rest of it was immaculate and it was only 8k. The seller said he had a LR tech diagnose it, and he said the high pressure fuel pumps needed replacing. I ordered 2 new Bosch pumps and installed them today. All the codes except for 2 went away, "low fuel pressure on the high pressure side" and "high fuel pressure on the low pressure side". Car is still in limp mode however, for about the first 10 seconds the car is running, it has full power. I don't think it is a mechanical fault, because the car works ok for the first 10 seconds, then becomes a complete slug. Could both the high pressure and low pressure fuel sensors be bad? The car doesn't misfire or anything, its normal aside from an extreme lack of power. Codes are P008B and P0087. Any ideas?
