I am having similar probs to the origional threads where idle revs jump between 1000-2500, but also with my 306 1.4 2001 "y" the
light is constantly on as well as the cooling fans and the temperature gauge reading hot, as i was advised by a garage and mechanic friend to change both temp sensors i have done and still nothing i have alos changed the alternator as mine wasnt kicking out enought juice! or so peugeot told me but this has done absolutely nout! in addition to the problems every now and again my rev counter, speedo and fuel gauge will jus drop out (but revs are still there as well as acceleration) The ABS light, Engine management light and the airbag light like to come on make the occasional xmas tree type effect in my car (which is lovely at this time of year!!!!) usually when im stood in traffic and as soon as revs are applied they go off?!?!?!?! as if by magic! but i have also experienced the loss of power and bunny hopping stuff aswell. Phew finished!!! any ideas please!!! greatly welcomed!!!.
