My peugeot 206 has been a nightmare since I got it 3 months ago! First of all the diagnostic light would come on and as it appeared the car would loose power for a second then carry on, this then become more frequent. Then I had the coil pack changed as the car was juddering and being sluggish. About a week later same syptoms happening took it back to garage and apparently it was a faulty coil pack so was replaced with a second one. Driving home again after this diagnostic light still appearing and misfiring, had new spark plugs fitted, the problem still occured. Then had first diagnostic test done and was told it was the fuel pump so had that changed. Car still experiencing problems ie. Would start from cold but after stopping and restarting from hot it would turn over but wouldnt start! A few times the car has completely died on me whilst driving, when this happenings all the lights on dash come on at same time then the car dies suddenly. Had a second diagnostic done and had filter changed, map sensor, and fuel temp gage? Drove from the garage parked up for 10 mins then again car would not start. Finally 3rd diagnostic apparently showed to be the actual ecu, had another ecu fitted and reprogrammed and also lambda, driving home from the garage, went to slow down for traffic and the car completely dies but started straight back up, then happened another time then finally got home, went back out to start it up guess what! Wont start! I cant even drive the car any more, it just judders lose of power, only starts if I put my foot on acelarator and at idle misfires but at high revs sounds fine, as soon as I take my foot off pedal when cars at low revs car just completely dies! Bought a new stepper motor and now the problem is that as soon as you turn engine on revs go straight to 3000 revs without even touching the pedals! PLEASE HELP AS IM AT MY WITS END!
