i had a faulty diesel injector on my 2.4jtd it had done 110000 miles.
the faults on a diesel are it sounds like a tractor as most new deisels run quite quiet, the engine shakes like mad, very bad mpg, unburned diesel smoke out exhaust when the injector fails and sometimes no fault will regester on the comp when hooked up. mine did not took months to find what was At Fault. i also advise to clean egr valve out on routine every 6 months as they are bad for sooting and sticking open.
im not sure the fault on petrol cars but im sure it will also have a missfiring problem and unspent fuel out of exhaust and lack of mpg.
listen for a clacking noise like the piece of plastic u used to put on ur back wheel of ur push bike. mine sounded like a more intense version than that. Ford Mondeo's are prone to injector faults in there deisels.
running cars on low dirty fuel is a major cause of these problems.
i would say to anyone put injector cleaner in and run high revs aslong as it does not sound too badly damaged it could just be a blocked injector and new injectors are not exactly cheap. mine cost £300 then the labour cost of fitting it
hope this helps for any unlucky people who have this fault.

∙ 14y agoA faulty fuel injector will usually result in the vehicle having a misfire on that specific cylinder. There are several ways to check if it is bad, one of them being to remove it and do a flow test on it. This requires hooking it up to a special machine that will simulate the conditions the fuel injector is under when it is installed in the vehicle.

∙ 11y agoRough running and very bad idle. They will also put more fuel into the cylinder than it can burn. The extra fuel will end up in the oil pan so your oil level will rise and it will smell like fuel. You can start the car and pressurize the fuel system. Shut the car off and watch the pressure at the fuel rail. If it drops too much either the injector or the pressure regulator check valve is faulty. If you have a cylinder that is misfiring, you can swap the injector from that cylinder with the injector of a cylinder that isn't and if the misfire moves that injector is bad.
