I am a new member of this forum as I have just acquired a 98 Atos GLS. It has a problem as it is hesitating to accelerate even when the engine is warm, it especially does it when accelerating from standstill, I have changed the plugs and checked the HT leads, but still the same, I have read that it could be the air flow sensor that needs to be cleaned/changed, problem is I don`t know exactly where I can find this sensor, if somebody could help by explaining or maybe posting a picture I would be greatful,
also my central lock system was working intermittently but suddenly it stopped, I have checked the fuses one by one to make sure that they are all ok, also checked the actual mechanism and cleaned the contacts of the central lock switch on drivers side door thinking it was a poor contact, but nothing, any ideas?
Cheers, Al

Map Sensor/TPS Sensor/Crankshaft sprocket pulley and or associated wiring. Sorry I have no wiring diagram to show you?. These sensors are onto of the manifold and on the side of the throttle housing

Thanks I`ll check these, also think that I sorted out the central lock problem, it has to be the door lock switch..... I will take it out and inspect it carefully!
anyway thanks again for your help
