Hi Lester, The injectors can be disconnected during operation. This can be carried out by disconnecting the electrical connector to each injector in turn. I believe the problem of a misfire will be more likely be a spark plug, or if your vehicle uses separate ignition coils for each plug, maybe one of those than any one of the injectors. The disconnections may cause fault codes to be recorded. You require to erase the codes afterwards. Regards John

SOURCE: misfires on low revs and slow running

Have you had a diagnostic check? This sounds more like a timing issue, I would have the plugs, plug wires and coils checked first before I get into the injectors.

SOURCE: Noisy engine on X type

I'm sorry but I only have information on the gasoline versions of this vehicle on my online resource.

Are you using diesel that is right for the season?

Most diesel engines are louder than gasoline engines as a rule.

injector realigning or recalibrating might work.

I have a miss in 4.5 v8 vdj79.maybe 1-2 injectors faulty.how do I make sure scv is working and does this make engine miss?


run the fault codes to be sure . missing is from injectors and low fuel pressure. If the rubbish got to the injectors you may have to pull then and have then professionally cleaned.

I have a 2002 Lincoln LS that up to 3000 rpm seems to run fine. at 3000, it starts to shudder and miss. any ideas/


If one of the engine components is acting up, you should get a check engine light and have codes for the components. If the light is not coming on, it could be a suspension or mechanical problem.
Low fuel pressure could also do it.

Audi 2.5tdi white smoke on exhaust low revs


Hi
White smoke is usually a good sign of un-burnt diesel so reading your post and all the things you have already changed ie the glow plugs I would have the injectors tested to make sure they are atomising properly as it sounds to me like when your car isn't under load ie at low revs you have a cylinder that isn't firing correctly
Hope this helps Nick

most misses are injector related either from dirty injectors , low fuel pressure ow injector wiring faults
use a quality injector cleaner for a tank or two
run the fault codes to check for other related sensor problems

I have a 2004 5 series 530I automatic. It misses when accelarating especially at low revs. The plugs are brand new, can anyone tell me whats wrong.


check the continuity of your plug wires and cap/ rotor contacts if applicable. Dirty injectors are also a possibility. A shop computer diagnostic would be a worthwhile investment to prevent further problems. Basics like fuel & air filters and clean throttlebody/ mass air flow sensor can all be contributing factors...Also check for leaking injector o-rings at intake manifold and fuel rail...
