Hi. I have a euro 4 that has done 164k miles. I'm having injector issues as we speak. the engine is effectively being starved of fuel. At that mileage it's likely the injectors are on there way out. How were the injectors checked? If it was a simple leak back test, that probably isn't enough. They need to be pressure tested to be absolutely sure they are knackered. A couple of simple tell tale signs are: 1. With the bonnet open and the engine running, does it appear like the engine is rocking violently as if an engine mount has broken? Or 2. With the drivers (or passenger) door open and engine running, does the door appear to bounce? If both are the case, the engine is probably running very lumpy and is struggling to breath, eat and !Removed! and wants to be turned off and never switched back on ever again!
Hope you get a result, damn fine car and !Removed! good engine as long as it's maintained
Cheers, Jarvo
