Hi guys I'm having some problems with my 2.5 turbo 4JA1-T, here in Costa Rica we have anual emmisions tests (the limit is 2.80m-1) 2 years ago my reading was 0.90 so it was pretty great, last year it made a huge change and climb to 9.90 it didnt pass, so I take it to a diesel shop they told me that my injectors were shot but they do something to it so I pass with 2.28 barely did it, but It has no pulling power It was scary slow and powerless so I open the injection pump and it was "fine".... yesterday I took the test again I close the pump before the test, and well it didnt pass againg 8.87.
I know that I have to change my Injectors but right now I can't afford it Its like 100 american dollars per injectors plus the diesel shop charge....,
But what really bothers me it's why the emmision went up that fast 9 point in one year, does the injectors die so fast??
It's anything else that can make my motor trow that high number? could the EGR be bad or something?
for the record
I got good fuel economy like 11km per liter
It doesnt burn a drop of oil
It starts great at cold morning at the first try
Thanks a lot for your help and your time for reading !
I'm kind of frustaded right now speccialy because of the change on the emmisions numbers
