Hello fellow stilo owners,
The stilo is a great car with a lot of features, i have a stilo 1.6 3dr from 2002 which i drove for a year without problems.. but now
My car is acting strange lately with fault codes p0105 and p1121 showing up. When i let the clutch come in at 20km/h in 2nd or 3rd gear without touching the throttle, the car shakes and the revs aren't constant. When i press the accelerator pedal nothing happens. I have to restart the car and then everything is fine for a while.
These fault codes have something to do with the throttle position sensor and MAP sensor i read on this forum. About half a year ago i cleaned the throttle body but haven't had any problems until now. Yesterday i disconnected the MAP sensor and cleaned the contacts with contact cleaner, i did the same for the connector on the throttle body(TPS ?). I also did a throttle relearn procedure according to T14's post in this thread: https://www.fiatforum.com/stilo/169469-1-6-no-throttle-limp-mode-ecu.html
When i disconnected the MAP sensor the car wasn't running good. With the MAP sensor connected it's running better but it holds back a little bit.
This morning the car stalled again at low revs with a cold start. When i hold up the revs everything is fine, it only holds back a little bit. The engine fault light is still on.
I did a search on this subject and read something about the D4 connector and the connection between ECU, throttle body and accelerator pedal potmeters. Should i clean all the D4 and ECU contacts with contact cleaner and how do i find them?
Do you think my problem is solved with a new MAP sensor?
What could this be?
Thanks in advance,
Tom
