Volvo post 1999 Marelli electronic throttle system(also known as ETS, or throttle body).

Symptoms: intermittently really rough idle, no power, car can do 20 mph only. Will correct with key off for a while, but leave engine management light on and re-occurs soon Most Volvo's post 1999 have Marelli throttle actuator. This is bringing the engine management light on and eventually putting car in limp home mode.


Ford Fiesta spi engine has problems with potentiometers and injector.

Symptoms and problems: (i) Throttle Position Sensor (TPS) reading to ECU is critical. These do fail
(ii) Throttle body not letting TPS come to rest at correct position
(iii) Wiring to ECU: plug problems have been known
(iv) Programming errors in ECU. Later software available.
(v) There are 2 idle speeds for the vehicle. One for stationary and one for moving. Moving idle speed may be corrupt. Recommend to check this by starting car, leave gearbox in neutral, and get strong friend to push you. As car gets above 11 mph if idle speed goes crazy, you have isolated problem.
