   I have some problems with my saxo, like stalling at traffic lights and in the morning when I try to drive the car for the first time. When I disconnect the MAP sensor is all perfect. I had that sensor replaced like 3 years ago so I am absolutely sure this causes all the problems.
   
   My question. If I just disconnect the MAP sensor can that cause any damage to the engine ?

   its gunna run like shit if i disconnect tht wen the ecu registers tht its missing itll stall cout out overfuel pop bang and whack the shit out of its self... if i were u id carb cleaner it put it bk on and take it get the diagnostics looked at and remove the fault code tht its more than likely going to throw up, and then have it working properly

   the sensor talks to the ecu telling it how much fuel and air to put in. if this is disconected the ecu still has a default amount to but in but ime sure after a while it will cause damage (under fueling)

   its more likley to over fuel on a safety map. I have a few spare map sensors here if you want one for £15?
