I've been suffering poor consumption for maybe 2,000 miles, down by possibly 30% at times.
Around that time I replaced the main crank pulley and weeping water pump, so I've been looking for something I disturbed/ didn't reinstate correctly, nothing found so far.
Brakes aren't binding.
Injectors new around 11k miles ago, and set up with DAS.
Air filter healthy.
Engine starts easily, runs well apart from being a little lumpy at tick over.
No codes.
But DAS does report that the EGR flow rate positioner has a malfunction.
The brakes aren't the keenest so I considered a vacuum issue. But I can't see how that would affect consumption.
Any ideas?
