hi i just changed every thing over in my 2wd saf to run stage 3 but when you give a sudden bit off throttle it miss fires, should all 3 bar map sensors have a vacum pipe off them and if so where does it go 2 as i think the one i got sold aint a 3 bar many thanks

 

Yes they should all have a vacum hose and the hose will go to the inlet manifold.
MAP= Manifold absalute pressure.

 

I think most 3 bar map sensors are grey in colour too.

 

Thanks i manage to sort it out it had the standard map sensor on it still i got given a throttle postion sensor and was told is was the 3 bar the cu*t lol

 

Make sure it is mounted correctly on the proper bracket so it looks upside down, ie the terminal plug goes upwards into it, and the pipe where the vaccy pipe goes points down.
