Hi all,

 

Well some may remember a while back that I had an issue with my car failing the balance test, well I had a compression test done and that showed results of between 175 and 168.

 

Now we swapped coil packs and plugs with no change although there was some corrosion on the plug and pack on cylinder 6 which is the one that is failing the test, this was cleaned but still have the problem.

 

There is a slight misfire on on tick over which is pointing to a problem althought the car seems to pull fine with no hesitation.

 

The misfire clears if I raise the fuel pressure by 7% in conzult but I couldn't tell you if this fixes the balance test issue as you can't run the test at the same time. So the first question is would low fuel pressure cause the balance test to fail?

 

Now the only thing that seems to be left is the injector and here lies the problem... to get to the injector means taking the Plenum off (I don't want to do the dremel method) but the issue is that I'm running Nismo 555 injectors. Now I can have them worked on and maybe that will fix them but I'm worried that it might not and then I'll be paying for the work to be done twice... So here's the next question, does anyone have a known good 555 injector that I could purchase or know where I can get one as I really don't want to buy a whole set just to replace one?

 

Thanks for all help in advance,

Shameless bump... Any Ideas anyone... Looks like I can get a single injector from Z1 but does anyone know if I can get a single from a UK distributer?

 

Thanks

Have you tried Jeff at Z world?

Hi mate,

I have spoken to him about this in the past as he used to look after the car for Radron who I bought it off, I feel a bit cheeky phoning him though as at the moment it's in the hands of Mr. F and it isn't really fair for me to hassle him if someone else has already taken it on as it were.

 

It will go to Jeffs at some point as I want some performance bits looked at and possibly a new diff but I don't want to drive up there with it as is as I'm afraid that I could do some damage if my fuel isn't combuting properly in that cylinder (it seems to drive perfectly well). I think I might initially try a VFPR and see if that clears it otherwise it'll be plenum off and injector replacement... If that doesn't work then god knows as then everything will have been looked at...

Thanks

Paul

Ahhh yeah i remember Radron hope you get it traced and sorted out, and yep i plan a trip there to one day for a good check over and some bits
