misfire low revs with P0120 code

Sometimes stalling car when taking off from standing start, have done washer bit, changed plugs , changed coil, cleaned out throttle housing, dismantled peddle and cleaned, is there a fuel filter and if so where? Pr can anybody give me suggestions, i am ok with it cause i know its there and compensate for it. , but it is driving my daughter mad as she just passed her test, thanks


Edit, OBD2 gives P0120

In the fuel tank, doesn't get changed, lasts the life of the engine.

I would check for codes with cheap OBD2 reader from here, it may pinpoint the fault more clearly rather than just changing parts on a whim.

KW808 OBD2 engine fault reader for the C3

As Arfur suggests, fault codes may shed light, also:-

What engine, age and mileage?

Do any warning lights appear on the dash (do the warning lights work)?

Is this a new problem?

If it is new, did it happen suddenly or come on gradually?

Does it make any difference if the engine is hot or cold?

52 reg 1.4 petrol, i am begining to think it may be a fuel mix prob , when the choke is on it runs fine seems to happen when choke goes off, OBD code P0120 throttle/pedal position sensor, can anybody tell me where this is ? e-bay selling one for £25 but cannot see where it fits, thanks

Do this for P0120:

Check the TPS connector (just cut off the connector and solder the wires together instead) which is in the passenger footwell, where the TPS would be on a left hand drive car.

Just done mine, the plug is quite high up in the (passenger) foot well behind the cover.
Mine was fixed to a bracket with a push on clip.
Hope this helps
