The ute is using a bit too much fuel. only done about 7000 k, and was getting awesome economy unloaded. Round town was getting about 9 to 9.5 l/100 and on highway 7.8 was achievable on a long run and 8.5 showed up after about a 30k run on highway. Now I'm getting 10.1 to 10.5 round town and 8.8 on highway, which turns into high nines and 10 again after a short time off the highway. Any attempt at heavy acceleration and you can watch the the fuel usage climb at a ridiculous rate. A typo at the start, should read 20,000 psi. A couple of traffic light stops and it's up to 10.5 again. About 10% increase in fuel. Have also noticed at idle the rail pressure at idle s about 35000 kpa which is about right but fluctuates 5 or 6 hundred above and below that constantly . I'm sure it used to be solid on 35 with no fluctuation.Turbo pressure is max at about 20psi, which would be pretty standard I think. Maf at idle is between 4.5 and 7.8 mostly between 5 and 7.5. Idle speed about 650 rpm with 70% egr.
Any advice appreciated.
