Hi,

I have problem with car. When I drive check engine light show up, on screen say engine fault, accelerating going slow, and wont go over 2000rpm.
First time that happened 3months ago. After that I cleaned throttle body and everything was fine. 3 weeks ago problem shows again.
I re-soldered pins on ecu, and car was run good. After 10days problem shows again. When I drive that error shows up and wont go over 2000rpm. I turn off the car and start again and car going good for next 1km and problem happened again.
I connected car on fiat examiner, and show possible errors: throttle body, MAP sensor, ECU and lambda sonda.

What you think, what I need to do to fix this problem?

Fiat stilo 1.6 16v Gasoline 5doors 2001.

Thanks in advance

Sounds like car is in 'limp mode' and therefore limiting g your speed to keep you safe.

So need to get fixing.

I know that. But what is the problem, why going in safe mode (limp mode)?
