Hi folks, bit of a problem with my engine it's a deisel 2.2 vtr 2004 when I start the engine it miss fires up to 2000 rpm with lots of blue smoke coming out of the exhaust once passed 2000 rpm it clears a seems to run ok could it be an injector sticking open .I have plugged one of the noid lights that flash to tell you that the signal for the injector is ok .also I took one of the 30amp fuses out of the bsi fuse 15 and it runs on all cylinders but in limp mode if I plug the fuse back in it runs on 2 or 3 again
Any help would be good thanks in advance

Next thing I would do is a leak back check on the injectors from cold.

I have tried that and they seem ok ..it's the bit with taking the 30amp fuse out of the bsi fuse 15 and it run on 4 cylinders in limp mode put it back in and it runs on 2 I was thinking more electrical fault
