Hello . Did you manage to fix this problem. I have Fiat Bravo 2008 1.6 105 diesel too. From a few weeks I am getting P0487 too. I cleared the throttle and the EGR valve but the error keeps coming again. Today I also received this P01EA error. Sometimes my car also have very unstable idle. When the idle is unstable my MAF reading go from below 2 g/s to 12-13 g/s. When the car is stable the MAF stays on 10.5 g/s which might be high for this car. I am planning on cleaning my MAF sensor. I hope you can provide some help. Thanks in advance!
