    My saxo 1.1i loses power and bogs down in the lower gears, also when stationary the car revs to about 2000rpm by itself then goes back down, someone please help !!!

    True, looking at all of 12hp?

    Mine used to rev slightly when idle for no reason but i left it and it stopped.

    OR it could be that the ecu has two maps on it and its flicking between the two? Haha jokes when you see that

    The cat idea is a possibility. I had a similar issue with my 316 compact a few yrs ago. Imagine the inside of the cat as a honeycomb with loads of holes, as it breaks up its possible for it to turn sideways which blocks all the airflow and will cause it to bog dramatically, when that happened on my bmw it was epic, it would just sit there idling no matter what i did with the pedal.

    Have a check around the engine for any loose or broken vacuum hoses too. Do it when the engine it cold tho so you can have a feel behind the engine. My sister has an old shape twingo that kept revving high, we bought an Idle control valve, a throttle position sensor, serviced it and stripped and cleaned the throttle body. Then we noticed that a hose had just fallen off, put it back on and it ran like a dream. A waste of £100 but a lesson to check the free stuff first!

    mine used to bog down, turned out to be the lambda sensor was goosed. changed it and it was fine since

    as for the idling, clean the ICV and adjust the cable
