Hi wonder if anyone could help my Fiat stilo 1.6 is Misfiring
It drops below 500 revs and starts to shake like its going to cut out

I did a code scan and came up with P0171 & P0141
I cleaned every single connector with electrical spray and still no luck

Can anyone give me a idea what i can do to fix this


Cheers

Both of these faults will show if you have a faulty lamba sensor. Check them both out, most probably pre-cat fault

P0141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
P0171 System Too Lean (Bank 1)
