What do you think about this problem on my fiat:
The car cranks well and is running but consumes to much fuel.
From the exhaust coming white maybe light gray exhaust gas.
When I check whit diag tool I have two DTC set:
- P0203
- P0141
Checked the injectors resistance and they are between 12-17 Ohm
When I checked whit oscilloscope the injector wires I have a problem
on the injector no 1 from the left side when I stand in front of the car.
Here are the signal's:
Bad signal, signal have some sort of noise.


Good signal from other injectors include the
injector which is described by the P0203 DTC, no noise.


I can not figure out why is this smoke on the exhaust...
Here is my smoke machine:


Any idea?
Could one of that two DTC codes cause this smoke monster?
