Hi All,
My fiat punto sporting mk2 has had an engine warning light on for a good few months now and i'm running out of ideas what to try.
When i check the ecu i get codes for the power steering (read about the D4 connector and this has not sorted the problem but this isnt my main issue), P1135 pre cat lambda sensor and a MAP barometer pressure fault.
Over the past few months I have had two new Lambda sensors (pre and post cat) and a new cat due to an incident with a speed bump but the error message does not go away.
Im getting around 27 mpg whereas i used to get 34-36 so the car is running rich. The car does not idle well sometimes stalls on startup.
As part of my new cat i also has a new exhaust system and the inside of the pipe is black and i get black smoke when revving at standstill.
It all makes the car sound very sick when you write it down like this. Does anybody have any suggestions why the car could be running rich and idleing badly?
Cheers
Tony
